	The&amp;nbsp;quasiparticle&amp;nbsp;band structures and optical properties of ACdTS kesterite are investigated here on the basis of first-principles calculations, including the many-body effects theory, by using the GW plus Bethe-Salpeter equation. There were significant GW-quasiparticle corrections, over 0.9&amp;nbsp;eV, to the GGA-Kohn-Sham band gap. Our calculations also show that ACdTS kesterite had a small binding energy, exhibited&amp;nbsp;optical absorption&amp;nbsp;in the visible region, high minority&amp;nbsp;carrier mobility, and large diffusion in length, rendering this material a promising candidate for solar cells. Based on these findings, we designed and implemented an ACdTS absorber in a thin-film solar cell (TFSC) structure. The new kesterite solar cell has a high efficiency of 11.6% with a low deficit in the output voltage. Moreover, a strategic combination between the&amp;nbsp;particle swarm optimization&amp;nbsp;approach and the ACdTS TFSC decorated with periodic nanowires is proposed to obtain significantly improved&amp;nbsp;photovoltaic&amp;nbsp;characteristics. The optimized design identifies a new pathway for a high conversion efficiency of 14%, far surpassing that provided by the conventional TFSC kesterite.

	Skin detection is very challenging because of the differences in illumination, cameras characteristics, the range of skin colours due to different ethnicities and many other variations. New effective and accurate methodologies are developed for skin colour detection to easily identify human's skin colour threw databases which are specifically designed to assist research in the area of face recognition. One of these is the recently built SFA database that showed high accuracy for segmentation of face images. The approach described in this paper exploits skin and non-skin samples provided by SFA for skin segmentation on the basis of the well-known Euclidean and Manhattan distance metrics. Most importantly, the scheme proposed tries to segment facial colour images inside or outside SFA by means of skin samples belonging to SFA. Simulation results in both SFA and UTD colour face databases indicate that detection rates higher than 95% can be achieved with either measure.

	In this work, an inverted PTB7:PC&lt;sub&gt;70&lt;/sub&gt;BM bulk&amp;nbsp;heterojunction&amp;nbsp;solar cells with the configuration of ITO/ZnO/ PTB7:PC&lt;sub&gt;70&lt;/sub&gt;BM / HTMs/Ag for various inorganic materials as a hole transport layer (ZnO, MoO&lt;sub&gt;3&lt;/sub&gt;, NiO, PEDOT: PSS, V&lt;sub&gt;2&lt;/sub&gt;O&lt;sub&gt;5&lt;/sub&gt;&amp;nbsp;and Cu&lt;sub&gt;2&lt;/sub&gt;O) are simulated by using the GPVDM software which is a free general-purpose tool for the simulation of opto-electronic devices. The influence of the thickness of both PTB7:PC&lt;sub&gt;70&lt;/sub&gt;BM and HTMs layers on the performance of the solar cell are investigated. The obtained results indicated that on regardless on the type of the inorganic material constituted the Hole Transport Material (HTM), the solar cell parameters can be improved by reducing the&amp;nbsp;HTM thickness&amp;nbsp;while the active layer optimum thickness is around 90&amp;nbsp;nm. The performance of the device with all inorganic materials used as HTM reaches the same levels as the PEDOT/PSS for the lower thickness (10&amp;nbsp;nm). As the thickness is increased, the electrical parameters are significantly enhanced by inserting&amp;nbsp;cuprous oxide&amp;nbsp;(Cu&lt;sub&gt;2&lt;/sub&gt;O) compared to the conventional PEDOT: PSS.

	A new multispectral InGaZnO (IGZO) thin-film phototransistor (TF PT) based on a graded band-gap (GBG) SiGe capping layer with&amp;nbsp;metallic nanoparticles&amp;nbsp;(MNPs) is proposed. An accurate drain-current model is developed to investigate the device performances, where the optical characteristics under different light excitations (530&amp;nbsp;nm, 820&amp;nbsp;nm, and 1550&amp;nbsp;nm) are analyzed using the 3-D Finite-difference time-domain method (FDTD). It is found that the proposed device shows high photoresponse characteristics. Besides, it is revealed that the GBG configuration, MNPs spatial distribution and size can induce a complex behavior, which influences the device photoresponse over multiple spectral bands. Importantly, an iterative decision-maker framework based on the Multi-Objective Genetic Algorithm (MOGA) metaheuristic approach is implemented to design efficient multispectral IGZO TF PT. It is demonstrated that the proposed MOGA-based scheme paves the way for the designer to identify the appropriate GBG profile and MNPs spatial distribution for highly-responsive devices at selective Visible and IR wavelengths and to realize high-performance multispectral sensors. The proposed approach based on combining the proposed IGZO TF PT structure with MOGA metaheuristic computation opens up a new strategy for the design and experimental fabrication of high-performance multispectral optoelectronic devices.

	In this paper, a new high-performance tunable band-selective (UV-Visible)&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/materials-science/photosensor&quot; title=&quot;Learn more about photodetector from ScienceDirect's AI-generated Topic Pages&quot;&gt;photodetector&lt;/a&gt;&amp;nbsp;(PD) based on RF sputtered a-SiC active layer is demonstrated. SiC thin-films were deposited on glass substrate by RF&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/materials-science/magnetron-sputtering&quot; title=&quot;Learn more about magnetron sputtering from ScienceDirect's AI-generated Topic Pages&quot;&gt;magnetron sputtering&lt;/a&gt;&amp;nbsp;method at different sputter power values ranging from 60&amp;nbsp;W to 120&amp;nbsp;W. The samples morphological, structural, optical and photodetection properties were investigated by carrying out XRD, SEM, EDS, UV-Vis spectroscopy and photoresponse measurements. It was revealed that the sputtering power could modulate the optical behavior of a-SiC alloy, tuning favorable visible absorbance at high sputter power. This phenomenon is correlated with the influence of the RF power on the SiC film structural properties and compositions. Interestingly, measurements showed that a-SiC PD elaborated at 60&amp;nbsp;W of RF power can detect UV radiation with a high responsivity of 138&amp;nbsp;mA/W, low noise effects, superior detectivity of 7.8&amp;nbsp;×&amp;nbsp;10&lt;sup&gt;12&lt;/sup&gt;&amp;nbsp;Jones, while maintaining the visible blindness property. On the other hand, the prepared device at high sputtering power exhibits extended photoresponse characteristics, yielding 426&amp;nbsp;mA/W and 77&amp;nbsp;mA/W of responsivity values over UV and visible ranges, respectively. Therefore, the present investigation can provide a new strategy for the design and fabrication of photodetector devices based on SiC platform with broadband and solar-blind adjustable sensing purposes according to the desired application.

	In this paper, the leaky acoustic microwaves (LAW) in a piezoelectric substrate (Lithium Niobate LiNbO3 Cut Y-X) were studied. The main method for this research was classification using a probabilistic neural network (PNN).The originality of this method is in the accurate values it provides. In our case, this technique was helpful in identifying undetectable waves, which are difficult to identify by classical methods. Moreover, all the values of the real part and the imaginary part of the coefficient attenuation with the acoustic velocity were classified in order to build a model from which we could easily note the Leaky waves. Accurate values of the coefficient attenuation and acoustic velocity for Leaky waves were obtained. Hence, in this study, the focus was on the interesting modeling and realization of acoustic microwave devices (radiating structures) based on the propagation of acoustic microwaves

	Cost-effective multispectral&amp;nbsp;photodetectors&amp;nbsp;(&lt;em&gt;PDs&lt;/em&gt;) exhibiting a high&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;Visible&lt;/em&gt;-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;photoresponse offer an avenue for developing environmental monitoring devices, imaging sensors, object discrimination, and optical links. However,&amp;nbsp;&lt;em&gt;PDs&lt;/em&gt;&amp;nbsp;based on a single semiconductor as light-sensitive layer are unable to provide broadband photodetection properties. In this work, a new&amp;nbsp;&lt;em&gt;PD&lt;/em&gt;&amp;nbsp;device based on&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;Microstructured Composite (&lt;em&gt;MC&lt;/em&gt;) which achieves a high&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;V&lt;/em&gt;isible-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;photoresponse is demonstrated. The&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;is elaborated by combining vacuum thermal evaporation technique and a suitable annealing process. Scanning Electron Microscopy (&lt;em&gt;SEM&lt;/em&gt;), energy-dispersive&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray spectroscopy (&lt;em&gt;EDS&lt;/em&gt;),&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray diffraction (&lt;em&gt;XRD&lt;/em&gt;), and&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;V&lt;/em&gt;is-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;spectroscopy were used to elucidate the morphological, structural and optical properties of the prepared sample. It was demonstrated that the&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;can be useful to enhance the visible absorbance efficiency by promoting efficient light-scattering effects. It is revealed that the prepared&amp;nbsp;&lt;em&gt;UV-Vis-NIR PD&lt;/em&gt;&amp;nbsp;offers a low dark current of&amp;nbsp;&lt;em&gt;5&amp;nbsp;nA&lt;/em&gt;, a high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;ratio of&amp;nbsp;&lt;em&gt;78&amp;nbsp;dB&lt;/em&gt;&amp;nbsp;and an enhanced responsivity in&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;, visible and&amp;nbsp;&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;ranges. The proposed multispectral&amp;nbsp;&lt;em&gt;PD&lt;/em&gt;&amp;nbsp;demonstrates a high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;current ratio under self-powered working regime. Therefore, the proposed&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;is believed to provide new insights in developing efficient, self-powered and low-cost multispectral&amp;nbsp;&lt;em&gt;PDs&lt;/em&gt;&amp;nbsp;for high-performance optoelectronic systems.

	In this paper, we propose a full-wave analysis for characterizing the resonant frequencies and bandwidths of high-temperature superconductor inverted microstrip printed on anisotropic substrates. Our proposed approach is based on Galerkin procedure in the Fourier transform domain (FTD) combining with the complex resistive boundary condition. With the use of suitable Green's functions in the FTD, the analysis is performed for the case where the superconducting rectangular patches printed on anisotropic substrate. The numerical results obtained using the proposed approach are compared with previously published numerical results computed by means of the electromagnetic simulator “IE3D software”. These comparisons were very good, which prove the correctness and the validity of the proposed method. It is found that the optical properties combined with optimally chosen structural parameters of anisotropic materials can be maintaining control of the resonant frequency and exhibiting wider bandwidth characteristics.

	In this study, an efficient full-wave method is developed for characterizing the resonant frequencies, bandwidths, and quality factors of an inverted circular superconducting patch antenna. Our technique is based on the Galerkin procedure in the Hankel transform domain (HTD) combined with the complex resistive boundary conditions. With the use of suitable Green’s functions in the HTD, the analysis is performed for the case where the superconducting circular patches is printed on an anisotropic substrate. The numerical results obtained using this approach are compared with the experimental results. These comparisons were very good, which proves the correctness and the validity of the method. It is found that the optical properties combined with optimally-chosen structural parameters of anisotropic materials can maintain control of the resonant frequency and exhibit wider bandwidth characteristics.

	In this work, an efficient analysis is presented to accurately predict the resonant frequency and bandwidth of superconducting microstrip antenna fed through a slot cut into the ground plane. The effect of the superconductivity of the rectangular patch is introduced in the Full-wave analysis based on Gorter-Casimir two fluid model together with London brothers equations. In order to check the accuracy of the proposed approach, the obtained results have been compared with theoretical and experimental data reported in the literature. Finally, the influence of the slot on the resonant frequency and half-power bandwidth of the superconducting antenna has been investigated.&amp;nbsp;

	This chapter focuses on double gate (DG) Tunneling Field Effect Transistor (TFET), having band engineering and high - k dielectrics. The basic structure of TFET device is derived and developed by p-i-n diode, containing two heavily doped degenerated semiconductor “p” and “n” regions and lightly doped intrinsic “i” region, respectively. The chapter explores the idea of high-k dielectric engineering as well as band engineering concept with DG -TFET. TFET is a type of field effect device in which current transport phenomena occur due to quantum tunneling between source and channel. The estimation of device characteristics and performance of TFET is time consuming and costly due to lack of rapid advancement in technology. TFET devices have become the most popular switching device among semiconductor players. The chapter summarizes the obtained results by popular device analysis technique, modeling and simulation of DG -TFET.

	In this paper, the role of introducing Germanium (Ge)/IGZO heterostructure in enhancing the Infrared (IR) photodetection properties of thin-film phototransistor (Photo- TFT) is presented. Numerical models for the investigated device are developed using ATLAS device simulator. The influence of Ge photosensitive layer thickness on the sensor IR photoresponse is carried out. It is revealed that the optimized IR Photo-TFT based on p-Ge/IGZO heterojunction can offer improved IR responsivity of 4.1×10(exp2) A/W, and over 10(exp6) of sensitivity. These improvements are attributed to the role of the introduced p-Ge/IGZO heterostructure in promoting IR photodetection ability and improved separation and transfer mechanisms of photo-exited electron/hole pairs. The photosensor is then implemented in an optical inverter gate circuit in order to assess its switching capabilities. It is found that the proposed phototransistor shows an improved optical gain thus indicating its excellent performance. Therefore, providing high IR responsivity and low dark noise effects, the optimized Ge/IGZO IR Photo-TFT can be a potential alternative photosensor for designing optoelectronic systems with high-performance and ultralow power consumption.

	In this paper, a new efficient and low-cost Schottky Diode (SD) based on a-Si/Ti structure was elaborated using RF magnetron sputtering technique. An exhaustive investigation of structural and electrical properties was performed, where the sputtered device was characterized using X-ray diffraction (XRD) and Keithley (4200-SCS) to measure the current-voltage characteristics. Moreover, a comprehensive study regarding the impact of the Ti layers on the device characteristics is carried out. It was demonstrated that implementing Ti intermediate layers could induce depletion regions at the interfaces, leading to significantly enlarged voltage barrier height. Furthermore, the elaborated SD exhibits a rectification behavior providing an appropriate current with a favorable ideality factor. This is mainly due to the reduced series resistance of the multilayer structure as confirmed by electrical analysis. Therefore, the proposed SD structure based on Ti intermediate layers provides improved performance and can open a new route for the fabrication of promising alternative devices for microelectronic and sensing applications.

	Tunnel FET is one of the promising devices advocated as a replacement of conventional MOSFET to be used for low power applications. Temperature is an important factor affecting the performance of circuits or system, so temperature associated reliability issues of double gate Tunnel FET and its impact on essential circuit design components have been addressed here. The temperature reliability investigation is based on double gate Tunnel FET, containing Si&lt;sub&gt;1-x&lt;/sub&gt;Ge&amp;nbsp;&lt;sub&gt;x&lt;/sub&gt;&amp;nbsp;/Si, source/channel and HfO&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;high-k gate dielectric material. During investigation, it has been found that at high temperature application range ~ 300&amp;nbsp;K - to - 600&amp;nbsp;K,the Tunnel FET device design parameters exhibit weak temperature dependency with switching current (I&lt;sub&gt;ON&lt;/sub&gt;), while the off-state current (I&lt;sub&gt;OFF&lt;/sub&gt;) is slightly varying ~10&lt;sup&gt;−17&lt;/sup&gt;A/μm-to-10&lt;sup&gt;−10&lt;/sup&gt;A/μm. In addition, the impact of temperature on various device design element such as V&lt;sub&gt;TH&lt;/sub&gt;(i.e.,switching voltage),on-current (I&lt;sub&gt;ON&lt;/sub&gt;), off-current (I&lt;sub&gt;OFF&lt;/sub&gt;), switching ratio (I&lt;sub&gt;ON&lt;/sub&gt;/I&lt;sub&gt;OFF&lt;/sub&gt;) and average subthreshold slope (i.e., SS&lt;sub&gt;avg&lt;/sub&gt;), ambipolar current (I&lt;sub&gt;AMB&lt;/sub&gt;) have been done in this research work.The essential circuit design components for digital and analog/RF applications, such as current amplification factor(g&lt;sub&gt;m)&lt;/sub&gt;&amp;nbsp;and its derivative (g&lt;sub&gt;m&lt;/sub&gt;’),the C-V components of device design, Cgg, Cgd and C&lt;sub&gt;gs&lt;/sub&gt;, cut - off frequency (ƒ&lt;sub&gt;T&lt;/sub&gt;) and gain band width (GBW) product have deeply investigated. In conclusion, the obtained results show that the designed double gate Tunnel FET device configuration and its circuit design components are suitable for ultra-low power circuit,system applications and reliable for hazardous temperature environment.

	The development of CZTS-based solar cells is limited by two factors, the low open circuit voltage and the conversion efficiency. This is why, in this study, the impact of Cu2ZnSnS4 (CZTS) absorber thin layer parameters on the performance of the proposed MoS2/CZTS/CdS/ZnO heterostructure is simulated by the standard software SCAPS-1D. The improving output performances of this structure; the open circuit voltage (Voc), the short circuit current density (Jsc), the fill factor (FF) and the efficiency (h) are obtained by varying the absorber layer thickness, acceptor carrier concentration NA and taking into account the effect of the electron work function of the back metal contact. The optimized cell provides an energy conversion efficiency of 15.23% (Voc = 0.99 V, Jsc = 21.89 mA/cm2, FF = 69.79%) for an optimal thickness of 2 μm, a doping of 1×1016 cm-3. Performance enhancement of the proposed solar cell is subject to the back metal contact, the optimal simulated value of 5.7 eV of which represents that of the Platinum’s work function Pt. The interest of this simulation makes it possible to adjust the solar cells dimensions, optimize the absorbent layers doping, choose appropriately the back metal contact and therefore help to considerably reduce the various recombination phenomena as well as the secondary phases.

	Among the causes of the degradation of the performance of kesterite-based solar cells is the wrong choice of the n-type buffer layer which has direct repercussions on the unfavorable band alignment, the conduction band offset (CBO) at the interface of the absorber/buffer junction which is one of the major causes of lower VOC. In this work, the effect of CBO at the interface of the junction (CZTS/Cd(1-x)ZnxS) as a function of the x composition of Zn with respect to (Zn+Cd) is studied using the SCAPS-1D simulator package. The obtained results show that the performance of the solar cells reaches a maximum values (Jsc = 13.9 mA/cm2 , Voc = 0.757 V, FF = 65.6%, ɳ = 6.9%) for an optimal value of CBO = -0.2 eV and Zn proportion of the buffer x = 0.4 (Cd0.6Zn0.4S). The CZTS solar cells parameters are affected by the thickness and the concentration of acceptor carriers. The best performances are obtained for CZTS absorber layer, thichness (d = 2.5 µm) and (ND = 1016 cm-3 ). The obtained results of optimizing the electron work function of the back metal contact exhibited an optimum value at 5.7 eV with power conversion efficiency of 13.1%, Voc of 0.961 mV, FF of 67.3% and Jsc of 20.2 mA/cm2 .

	The numerical simulation tool SCAPS-1D was used to analyze perovskite solar cell having the architecture ITO/ PEDOT:PSS or GO /CH3NH3PbI3-xClx/ PCBM /Au contains inverted planar hetero-junction device. In this work, we investigated the effect of inserting the Graphene Oxide (GO) as Hole Transport layer (HTL) on the performance of perovskite solar cells. Simulation results show that the use of GO as a hole transport layer is efficient. The efficiency of PSCs based on GO HTL was increased by about 1.6 % compared to the conventional PEDOT:PSS HTL device. The obtained results of optimizing the thickness of GO HTL exhibited an optimum value around 10 nm with an efficiency of 12.35 %, Voc of 1.19 V and FF of 54.8 %. We have also shown that the performance of device for high GO carrier density is a better than with low ones. In addition, increasing the temperature beyond the optimum value obtained around 320 K for both HTL materials (GO and PEDOT:PSS) has detrimental effect on the performance of the perovskite solar cells however the device is more sensitive to the temperature with PEDOT:PSS than the GO ones. The effect of band gap of GO on the performance of device is also studied. The obtained results underline the determining role playedby this parameter with an optimum value around 3.25 eV.

	Phosphorus nickel alloy, intended for anticorrosion coating, was prepared and deposited at room temperature on copper substrate by chronoamperometry technique in a sulphate bath. The effect of potential on the chemical composition, nucleation and growth, the structure and surface morphology during the electrodeposition of this alloy was presented in this work. X-ray microanalysis showed that the content of phosphorus in the prepared alloys decreases with increasing cathodic potential. Chronoamperograms analysis indicated that the nucleation process is instantaneous and of three-dimensional (3D) growth and is controlled by kinetics. X-ray diffraction analysis revealed an amorphous structure while SEM images showed a smooth appearance with pore presence.

	In this paper, the optimization, elaboration and characterization of an efficient spectral&amp;nbsp;beam splitter&amp;nbsp;based on a simple RF sputtered ITO/Ag/ITO (IAI) ultra-thin multilayer structure are presented. An experimental investigation assisted by&amp;nbsp;Genetic Algorithm&amp;nbsp;(GA) metaheuristic optimization was carried out to achieve high-performance spectral splitter for tandem solar cell applications. The RF&amp;nbsp;magnetron sputtering&amp;nbsp;method was used to elaborate the optimized IAI structure. The optical and structural properties of the sputtered splitter were also analyzed using UV–Vis-IR spectroscopy and X-ray diffraction (XRD) measurements. It is found that the elaborated splitter structure offers 84% of transparency and a high reflectance of 87% with an optimum cut-off wavelength of 800&amp;nbsp;nm. This is attributed to the design approach, which leads to promote spectral splitting mechanism by inducing efficient&amp;nbsp;optical modulation. Interestingly, a new Figure of Merit (FoM) parameter, which evaluates the optical splitting performances is proposed. Moreover, a new Perovskite/InGaAs tandem cell is proposed and analyzed to show the impact of the elaborated spectrum splitter on the solar cell efficiency. It is revealed that the investigated solar cell exhibits an improved efficiency approaching 30%. The latter value far surpasses that provided by&amp;nbsp;Perovskite&amp;nbsp;tandem cells. These results indicate that our spectrum splitting approach can open a new pathway towards designing high-performance tandem&amp;nbsp;photovoltaic devices.

	High-performance multispectral&amp;nbsp;photodetectors&amp;nbsp;(PDs) are highly attractive for the emerging optoelectronic applications. In this work, a new broadband PD based on&amp;nbsp;&lt;em&gt;p&lt;/em&gt;-NiO/Ag/n-ITO&amp;nbsp;heterostructure&amp;nbsp;was fabricated by RF&amp;nbsp;magnetron sputtering&amp;nbsp;technique at room temperature. The tri-layered structure offering multispectral detection property was first identified using theoretical calculations based on combined FDTD and Particle Swarm Optimization (PSO) techniques. The crystal structure of the elaborated sensor was analyzed using X-ray diffraction (XRD) method. The device optical properties were investigated by UV–Vis–NIR spectroscopy. The NiO/Ag/ITO heterostructured PD shows a high average absorbance of 63% over a wide spectrum range of [200&amp;nbsp;nm–1100nm]. Compared with NiO and ITO thin-films, the performances of the heterostructured device are considerably enhanced. It was found that the prepared PD with NiO/Ag/ITO heterostructure merges the benefits of multispectral photodetection with reduced&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/materials-science/optical-loss&quot; title=&quot;Learn more about optical losses from ScienceDirect's AI-generated Topic Pages&quot;&gt;optical losses&lt;/a&gt;&amp;nbsp;and efficient transfer of photo-induced carrier. The device demonstrated a high I&lt;sub&gt;ON&lt;/sub&gt;/I&lt;sub&gt;OFF&lt;/sub&gt;&amp;nbsp;ratio of 78&amp;nbsp;dB and an enhanced responsivity under UV, visible and NIR lights (171&amp;nbsp;mA/W at 365&amp;nbsp;nm, 67&amp;nbsp;mA/W at 550&amp;nbsp;nm and 93&amp;nbsp;mA/W at 850&amp;nbsp;nm). The broadband photodetection property enabled by the optimized NiO/Ag/ITO heterostructure opens a new route for the elaboration of low-cost devices that can offer multiple sensing purposes, which are highly suitable for optoelectronic applications.

	In this work, a new Ultraviolet Optically Controlled Graphene Field-Effect Transistor (&lt;em&gt;UV-OC-GFET&lt;/em&gt;) based on Graded Band-Gap (&lt;em&gt;GBG&lt;/em&gt;)&amp;nbsp;&lt;em&gt;ZnMgO&lt;/em&gt;&amp;nbsp;photosensitive-gate is proposed. The device drain current model is numerically developed by self-consistently solving the Schrödinger/Poisson equations based on non-equilibrium Green's function (&lt;em&gt;NEGF&lt;/em&gt;) formalism. The influence of&amp;nbsp;&lt;em&gt;GBG&lt;/em&gt;&amp;nbsp;strategy with different profiles on the device sensing performances is analyzed. Our investigation reveals that the use of both&amp;nbsp;&lt;em&gt;GBG ZnMgO&lt;/em&gt;&amp;nbsp;photo-gate and graphene nanoribbon channel offers the dual-benefit of improved electric field distribution in the photosensitive layer and enhanced drain current. This leads to outperforming the device Figure of Merits (&lt;em&gt;FoMs&lt;/em&gt;). In this context, it is found that the proposed&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;&amp;nbsp;sensor with optimized band-gap profile exhibits giant responsivity exceeding&amp;nbsp;&lt;em&gt;1.5 × 10&lt;sup&gt;6&lt;/sup&gt;&lt;/em&gt;&amp;nbsp;A/W with superb detectivity of&amp;nbsp;&lt;em&gt;7 × 10&lt;sup&gt;14&lt;/sup&gt;&amp;nbsp;Jones&lt;/em&gt;, far surpassing that of the conventional&amp;nbsp;&lt;em&gt;Si&lt;/em&gt;-channel based phototransistors. Therefore, this innovative strategy based on graphene nanoribbon channel combined with&amp;nbsp;&lt;em&gt;GBG&lt;/em&gt;&amp;nbsp;sensitive-gate pinpoints a new path towards achieving high-performance visible-blind&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-phototransistor, making it a potential alternative photoreceiver for chip-level optical communication and optoelectronic applications.

	In this paper, embedded amorphous-silicon (&lt;em&gt;a-Si&lt;/em&gt;) and titanium (&lt;em&gt;Ti&lt;/em&gt;) ultrathin-films forming a multilayer structure is proposed as a new efficient absorber material for thin-film solar cells (&lt;em&gt;TFSCs&lt;/em&gt;). Promising design strategy based on combining&amp;nbsp;&lt;em&gt;FDTD&lt;/em&gt;&amp;nbsp;(&lt;em&gt;finite difference time domain&lt;/em&gt;) with particle swarm optimization (&lt;em&gt;PSO&lt;/em&gt;) was adopted to identify the&amp;nbsp;&lt;em&gt;a-Si/Ti&lt;/em&gt;&amp;nbsp;multilayer structure offering the highest total absorbance efficiency (&lt;em&gt;TAE&lt;/em&gt;). It is found that the proposed multilayer structure can serve as an effective absorber, yielding superb&amp;nbsp;&lt;em&gt;TAE&lt;/em&gt;&amp;nbsp;exceeding&amp;nbsp;&lt;em&gt;80%&lt;/em&gt;. The&amp;nbsp;&lt;em&gt;a-Si/Ti&lt;/em&gt;&amp;nbsp;multilayer was then elaborated by successive growth of&amp;nbsp;&lt;em&gt;a-Si&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;Ti&lt;/em&gt;&amp;nbsp;ultrathin layers using&amp;nbsp;&lt;em&gt;RF&lt;/em&gt;&amp;nbsp;magnetron sputtering technique. The sputtered&amp;nbsp;&lt;em&gt;a-Si/Ti&lt;/em&gt;&amp;nbsp;thin-film was characterized by scanning electron microscopy (&lt;em&gt;SEM&lt;/em&gt;),&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray diffraction (&lt;em&gt;XRD&lt;/em&gt;), and&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;–visible absorption spectroscopy. Measurements showed a unique optical behavior, promoting broadband absorbance over the visible and even&amp;nbsp;&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;spectrum ranges. In particular, the prepared&amp;nbsp;&lt;em&gt;a-Si/Ti&lt;/em&gt;&amp;nbsp;absorber exhibits an optical band-gap of&amp;nbsp;&lt;em&gt;1.36&amp;nbsp;eV&lt;/em&gt;, which is suitable for photovoltaic applications. A performance assessment of the elaborated absorber was investigated by extracting&amp;nbsp;&lt;em&gt;I-V&lt;/em&gt;&amp;nbsp;characteristics and electrical parameters under dark and&amp;nbsp;&lt;em&gt;1-sun&lt;/em&gt;&amp;nbsp;illumination. It is revealed that the proposed absorber demonstrates outstanding electrical and sensing performances. Therefore, promoting enhanced resistive behavior and light-scattering effects, this innovative concept of optimized&amp;nbsp;&lt;em&gt;a-Si/Ti&lt;/em&gt;&amp;nbsp;multilayer provides a sound pathway for designing promising alternative absorbers for the future development of&amp;nbsp;&lt;em&gt;a-Si&lt;/em&gt;-based&amp;nbsp;&lt;em&gt;TFSCs&lt;/em&gt;.

	The rapid progress of wide band gap SiC semiconductor material opens up new opportunities to develop efficient monolithically integrated ultraviolet (UV) photonic and power systems for a wide range of advanced applications. In this paper, low-noise solar-blind UV&amp;nbsp;photodetector&amp;nbsp;(PD) based on all-amorphous ZnO/SiC&amp;nbsp;heterostructure&amp;nbsp;was fabricated via RF&amp;nbsp;magnetron sputtering&amp;nbsp;technique. The device structural and optical properties were investigated before and after thermal treatment at different annealing temperature values varying from 300&amp;nbsp;°C to 600&amp;nbsp;°C. UV-Visible&amp;nbsp;spectroscopy revealed that the annealing process has a beneficial effect in terms of high UV absorbance and solar-blindness properties. Photoelectrical characterization demonstrated the high UV photoresponse and low dark noise of the prepared UV PD based on all-amorphous ZnO/SiC structure. Improvement of the device performances were achieved by an appropriate annealing process. After post-annealing, the thermally treated ZnO/SiC UV PD at 500&amp;nbsp;°C exhibits a high detectivity of 2.4&amp;nbsp;×&amp;nbsp;10&lt;sup&gt;12&lt;/sup&gt;&amp;nbsp;Jones, high&amp;nbsp;signal to noise ratio&amp;nbsp;of 2.64×10&lt;sup&gt;5&lt;/sup&gt;&amp;nbsp;and a giant UV–Vis&amp;nbsp;rejection ratio of 5.9&amp;nbsp;×&amp;nbsp;10&lt;sup&gt;3&lt;/sup&gt;. Therefore, the present study may provide new perspectives for fabricating ultralow dark noise solar-blind UV PD based on all-amorphous ZnO/SiC heterostructure, which promotes the development of integrated UV photonic systems based on SiC platform.

	Cost-effective multispectral&amp;nbsp;photodetectors&amp;nbsp;(&lt;em&gt;PDs&lt;/em&gt;) exhibiting a high&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;Visible&lt;/em&gt;-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;photoresponse offer an avenue for developing environmental monitoring devices, imaging sensors, object discrimination, and optical links. However,&amp;nbsp;&lt;em&gt;PDs&lt;/em&gt;&amp;nbsp;based on a single semiconductor as light-sensitive layer are unable to provide broadband photodetection properties. In this work, a new&amp;nbsp;&lt;em&gt;PD&lt;/em&gt;&amp;nbsp;device based on&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;Microstructured Composite (&lt;em&gt;MC&lt;/em&gt;) which achieves a high&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;V&lt;/em&gt;isible-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;photoresponse is demonstrated. The&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;is elaborated by combining vacuum thermal evaporation technique and a suitable annealing process. Scanning Electron Microscopy (&lt;em&gt;SEM&lt;/em&gt;), energy-dispersive&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray spectroscopy (&lt;em&gt;EDS&lt;/em&gt;),&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray diffraction (&lt;em&gt;XRD&lt;/em&gt;), and&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;V&lt;/em&gt;is-&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;spectroscopy were used to elucidate the morphological, structural and optical properties of the prepared sample. It was demonstrated that the&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;can be useful to enhance the visible absorbance efficiency by promoting efficient light-scattering effects. It is revealed that the prepared&amp;nbsp;&lt;em&gt;UV-Vis-NIR PD&lt;/em&gt;&amp;nbsp;offers a low dark current of&amp;nbsp;&lt;em&gt;5&amp;nbsp;nA&lt;/em&gt;, a high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;ratio of&amp;nbsp;&lt;em&gt;78&amp;nbsp;dB&lt;/em&gt;&amp;nbsp;and an enhanced responsivity in&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;, visible and&amp;nbsp;&lt;em&gt;NIR&lt;/em&gt;&amp;nbsp;ranges. The proposed multispectral&amp;nbsp;&lt;em&gt;PD&lt;/em&gt;&amp;nbsp;demonstrates a high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;current ratio under self-powered working regime. Therefore, the proposed&amp;nbsp;&lt;em&gt;ZnO-ZnS MC&lt;/em&gt;&amp;nbsp;is believed to provide new insights in developing efficient, self-powered and low-cost multispectral&amp;nbsp;&lt;em&gt;PDs&lt;/em&gt;&amp;nbsp;for high-performance optoelectronic systems.

	In this paper,&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;composite structure is proposed as a new efficient and earth-abundant absorber material for thin-film solar cells (&lt;em&gt;TFSCs&lt;/em&gt;). Promising elaboration strategy based on combining vacuum thermal evaporation technique and oxidation process under an annealing temperature of&amp;nbsp;&lt;em&gt;500&amp;nbsp;°C&lt;/em&gt;&amp;nbsp;was used to prepare&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;composite with high sun-light absorption capabilities. The fabricated microstructure was then characterized by Scanning Electron Microscopy (&lt;em&gt;SEM&lt;/em&gt;), energy-dispersive&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray spectroscopy (&lt;em&gt;EDS&lt;/em&gt;),&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-ray diffraction (&lt;em&gt;XRD&lt;/em&gt;), and&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;–&lt;em&gt;V&lt;/em&gt;isible absorption spectroscopy. The influence of the annealing time on the structural and optical performances of the prepared samples was investigated. Surface analysis demonstrated the&amp;nbsp;&lt;em&gt;ZnO&lt;/em&gt;&amp;nbsp;decoration of&amp;nbsp;&lt;em&gt;ZnS&lt;/em&gt;&amp;nbsp;thin-film, where&amp;nbsp;&lt;em&gt;SEM&lt;/em&gt;&amp;nbsp;images showed dense and pinhole-free&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;composite with micrometer-sized grains and a few voids visible at thin-films surface. Optical characterization showed that the prepared thin-film absorber exhibits an optical band-gap of&amp;nbsp;&lt;em&gt;2.65&amp;nbsp;eV&lt;/em&gt;&amp;nbsp;with a high Total Absorption Efficiency (&lt;em&gt;TAE&lt;/em&gt;) of&amp;nbsp;&lt;em&gt;62%&lt;/em&gt;&amp;nbsp;and an absorption coefficient exceeding&amp;nbsp;&lt;em&gt;2&amp;nbsp;×&amp;nbsp;10&lt;sup&gt;4&lt;/sup&gt;&amp;nbsp;cm&lt;sup&gt;−1&lt;/sup&gt;&lt;/em&gt;. In addition,&amp;nbsp;&lt;em&gt;I-V&lt;/em&gt;&amp;nbsp;characteristics under dark and&amp;nbsp;&lt;em&gt;1-sun&lt;/em&gt;&amp;nbsp;illumination of the microstructured&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;composite were extracted. It was revealed that the proposed absorber showcases a high visible photoresponse. Therefore, promoting effective light-scattering effects, this innovative&amp;nbsp;&lt;em&gt;ZnO-ZnS&lt;/em&gt;&amp;nbsp;composite offers a sound pathway to prepare alternative low-cost absorbers for the future development of&amp;nbsp;&lt;em&gt;TFSCs&lt;/em&gt;.

	Laser communication between satellites in the constellation and from the satellites to ground stations offers a gigantic data rate for the users. This principal advantage drives telecom companies to develop this technology to use it like a carrier signal, the most disadvantage of this technology is the need to very complicated pointing systems between the transmitter and the receiver due to a very small beam divergence, continually moving of satellites in orbits and the distance between the satellites (tens of thousands of kilometers). The laser beam suffers continuously from several factors like atmospheric turbulences, internal and external vibrations. All these factors lead to an increase in the bit errors rate and cause degradation in the communication quality. This paper deals with a new method of modelisation of external effects in transmission of signal light from a ground station to the satellite through atmospheric disturbances. Indeed, an in-depth investigation, of the influences of satellite vibrationsinlaser signal transmission between satellites constellation, has been conducted by studying the effect of the intensity of vibrations on the optical signal amplitude. Some solutions are proposed to improve the efficiency of optical satellites communications.

	To boosting the performance of inverted p-i-n-type planar hetero-junction architecture photovoltaic cells based on CH&lt;sub&gt;3&lt;/sub&gt;NH&lt;sub&gt;3&lt;/sub&gt;PbI&lt;sub&gt;3&lt;/sub&gt;&amp;nbsp;perovskite materials, a thin buffer layer Bathocuproine (BCP) is introduced between the Electron Transporting Layer (ETL) PCBM and the metal contact. The trends in parameters Perovskite Solar Cells (PSCs) inserting BCP is studied using solar cell capacitance simulator (SCAPS-1D). The obtained results of optimizing the thickness of the Bathocuproine (BCP) buffer layer exhibited optimum value at 5 nm, with power conversion efficiency (PCE) of 17.30 %,&amp;nbsp;&lt;em&gt;V&lt;sub&gt;OC&lt;/sub&gt;&amp;nbsp;&lt;/em&gt;of 1.39 V, and FF of 62.89 %. The carrier concentration was higher than 10&lt;sup&gt;17&lt;/sup&gt;&amp;nbsp;cm&lt;sup&gt;-3&lt;/sup&gt;&amp;nbsp;increases sharply the conversion efficiency by about 0.35-2.3 %. Further, the lower metal work function (Ф&lt;sub&gt;m&lt;/sub&gt;&amp;lt;4.3 eV) enhances the electrical parameters where the efficiency up to 21.3 %.

	Zinc Oxide (ZnO) and Nickel Oxide (NiO)&amp;nbsp;thin films&amp;nbsp;were prepared using the&amp;nbsp;spray pyrolysis&amp;nbsp;technique using three different quantities of solution 5, 10, and 15&amp;nbsp;ml, to modify their optical properties. Optical characterization of the obtained thin films showed that the bandgap and the transparency of NiO and ZnO decrease with increasing solution quantity. The films are highly transparent making them suitable for optoelectronic applications. It is worth noting that NiO has a low growth rate compared to ZnO due to its larger bandgap. The different parameters obtained for both films are then used to simulate the electrical characteristics and the responsivity of a NiO/ZnO&amp;nbsp;heterojunction&amp;nbsp;based PN&amp;nbsp;photodiode. Both the electrical characteristics and the responsivity improve with increasing quantities of solution. These findings may help to find an optimal design for photodiode fabrication.

	In this paper, novel self-powered, solar-blind&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;&amp;nbsp;photodetector&amp;nbsp;(&lt;em&gt;PD&lt;/em&gt;) designs based on a&amp;nbsp;&lt;em&gt;ZnO&lt;/em&gt;&amp;nbsp;thin-film with engineered back metal layer (&lt;em&gt;BML&lt;/em&gt;) were fabricated by&amp;nbsp;&lt;em&gt;RF&lt;/em&gt;&amp;nbsp;magnetron sputtering&amp;nbsp;and e-beam evaporation techniques. An exhaustive study concerning the impact of dissimilar&amp;nbsp;&lt;em&gt;BML&lt;/em&gt;&amp;nbsp;(&lt;em&gt;Au&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;Ni&lt;/em&gt;) on the device structural, optical and electrical properties was carried out. The measured&amp;nbsp;&lt;em&gt;I–V&lt;/em&gt;&amp;nbsp;curves illustrated an asymmetrical behavior, enabling a clear and distinctive&amp;nbsp;photovoltaic&amp;nbsp;mode. Superb sensitivity of&amp;nbsp;&lt;em&gt;10&lt;/em&gt;&lt;sup&gt;&lt;em&gt;7&lt;/em&gt;&lt;/sup&gt;&lt;em&gt;,&lt;/em&gt;&amp;nbsp;high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;ratio of 149dB, ultralow dark-noise current less than&amp;nbsp;&lt;em&gt;11pA&lt;/em&gt;&amp;nbsp;and&amp;nbsp;responsivity&amp;nbsp;exceeding&amp;nbsp;&lt;em&gt;0.&lt;/em&gt;27A/W were reached for the prepared&amp;nbsp;&lt;em&gt;ZnO-&lt;/em&gt;based&amp;nbsp;&lt;em&gt;UV-PDs&lt;/em&gt;&amp;nbsp;in self-powered mode. The role of the engineered&amp;nbsp;&lt;em&gt;BML&lt;/em&gt;&amp;nbsp;in promoting effective separation and transfer of the photo-induced carriers was discussed using the band-diagram theory. The influence of the&amp;nbsp;annealing process&amp;nbsp;on the&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-sensor performance was also investigated. The annealed device at&amp;nbsp;&lt;em&gt;500°C&lt;/em&gt;&amp;nbsp;demonstrated a lower dark current of a few picoamperes and a high rejection ratio of&amp;nbsp;&lt;em&gt;2.2×10&lt;/em&gt;&lt;sup&gt;&lt;em&gt;3&lt;/em&gt;&lt;/sup&gt;&lt;em&gt;,&lt;/em&gt;&amp;nbsp;emphasizing its exciting visible blindness characteristics&lt;em&gt;.&lt;/em&gt;&amp;nbsp;Therefore, the use of an engineered&amp;nbsp;&lt;em&gt;BML&lt;/em&gt;&amp;nbsp;with optimized annealing conditions open up new perspectives to realizing high-performance, self-powered solar-blind&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;-&lt;em&gt;PDs&lt;/em&gt;&amp;nbsp;based on simple thin-film&lt;em&gt;-ZnO&lt;/em&gt;&amp;nbsp;structure strongly desirable for various optoelectronic applications.

	The mechanical behavior of few-layered borophene (&lt;i&gt;η&lt;/i&gt;-LB), at different temperatures ranging from 10 to 800 K in conjunction with a variant strain-rate, is studied by employing molecular dynamics simulations based on the Stillinger-Weber potential. The uniaxial tensile deformations along the zigzag- and armchair-direction of the hexagonal lattice are considered for&amp;nbsp;&lt;i&gt;η&lt;/i&gt;-LB, with&amp;nbsp;&lt;i&gt;η&lt;/i&gt;&amp;nbsp;= 1, 2, 3, 4. We find an extremely anisotropic mechanical response. Parameters such as Young’s modulus and fracture strength are higher along the armchair-traction than the zigzag one due to the corrugated structure along the zigzag-axis. The fracture resistances of&amp;nbsp;&lt;i&gt;η&lt;/i&gt;-LB are strongly sensitive to temperature, while their dependence on the strain-rate is relatively low. The influence of nitrogen intercalation as well as vacancy defects on elastic behavior is also determined and discussed. The results are significantly affected by the defect’s type, concentration, and location. Our findings provide useful insights for the design of LB for many applications requiring a practical large magnitude strain engineering.

The proposed structure consists on sputtering an&amp;nbsp;&lt;em&gt;ITO&lt;/em&gt;&amp;nbsp;thin-film acting as a passivation layer on the&amp;nbsp;&lt;em&gt;a-Si&lt;/em&gt;&amp;nbsp;layer to form a&amp;nbsp;heterostructure&amp;nbsp;design compatible with silicon photonics technology.&amp;nbsp;&lt;em&gt;X&lt;/em&gt;-Ray Diffraction (&lt;em&gt;XRD&lt;/em&gt;) and&amp;nbsp;&lt;em&gt;UV–Vis&lt;/em&gt;&amp;nbsp;spectra were carried out to assess the device structural and optical properties. Measurements emphasized the amorphous state of the sputtered&amp;nbsp;&lt;em&gt;Si&lt;/em&gt;&amp;nbsp;thin-film. Interestingly, it was found that the elaborated device shows an exciting&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;&amp;nbsp;absorption capability (over than&amp;nbsp;&lt;em&gt;95%&lt;/em&gt;) with drastically reduced visible photoresponse. The elaborated&amp;nbsp;&lt;em&gt;ITO/a&lt;/em&gt;-&lt;em&gt;Si UV PD&lt;/em&gt;&amp;nbsp;exhibits an ultra-low dark current less than&amp;nbsp;&lt;em&gt;1&amp;nbsp;pA&lt;/em&gt;, a good responsivity of&amp;nbsp;&lt;em&gt;0.&lt;/em&gt;13 A/W and a high&amp;nbsp;&lt;em&gt;I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;ON&lt;/em&gt;&lt;/sub&gt;&lt;em&gt;/I&lt;/em&gt;&lt;sub&gt;&lt;em&gt;OFF&lt;/em&gt;&lt;/sub&gt;&amp;nbsp;ratio of&amp;nbsp;&lt;em&gt;2.5&amp;nbsp;×&amp;nbsp;10&lt;/em&gt;&lt;sup&gt;&lt;em&gt;4&lt;/em&gt;&lt;/sup&gt;. Besides, the device demonstrates a high&amp;nbsp;&lt;em&gt;UV-to-Vis&lt;/em&gt;&amp;nbsp;ratio exceeding&amp;nbsp;&lt;em&gt;2.3&amp;nbsp;×&amp;nbsp;10&lt;/em&gt;&lt;sup&gt;&lt;em&gt;3&lt;/em&gt;&lt;/sup&gt;, thus confirming its visible blindness property. These enhancements are attributed to the role of&amp;nbsp;&lt;em&gt;ITO/a-Si&lt;/em&gt;&amp;nbsp;heterostructure&amp;nbsp;in promoting near-perfect&amp;nbsp;&lt;em&gt;UV&lt;/em&gt;&amp;nbsp;absorption. In addition, this structure generates an electric field acting as effective driving force of the photo-induced&amp;nbsp;&lt;em&gt;e/h&lt;/em&gt;&amp;nbsp;pairs, which leads to enhance the device generation/collection efficiency. Therefore, the use of&amp;nbsp;&lt;em&gt;ITO/a-Si&lt;/em&gt;&amp;nbsp;design opens up new pathways for designing novel solar-blind&amp;nbsp;&lt;em&gt;UV PDs&lt;/em&gt;&amp;nbsp;potentially appropriate for integrated silicon photonics technology.

	This work aims to investigate the performance of a new Junctionless (&lt;em&gt;JL&lt;/em&gt;)&amp;nbsp;&lt;em&gt;Ge&lt;/em&gt;-gate Tunneling&lt;em&gt;-FET&lt;/em&gt;&amp;nbsp;phototransistor&amp;nbsp;for Infrared sensing applications. The electrical and optical performances of the considered sensor are numerically analyzed, where both switching and optoelectronic properties are reported. In this context, we address the influence of the&amp;nbsp;&lt;em&gt;Ge&lt;/em&gt;-gate doping level and high-&lt;em&gt;k&lt;/em&gt;&amp;nbsp;gate dielectric&amp;nbsp;on the variation of optical Figures-of-Merit (&lt;em&gt;FoMs&lt;/em&gt;) parameters such as&amp;nbsp;responsivity,&amp;nbsp;&lt;em&gt;I&lt;sub&gt;ON&lt;/sub&gt;/I&lt;sub&gt;OFF&lt;/sub&gt;&lt;/em&gt;&amp;nbsp;ratio and optical commutation speed. Interestingly, it was revealed that the proposed design provides promising pathways for enhancing the phototransistor&amp;nbsp;&lt;em&gt;FoMs&lt;/em&gt;&amp;nbsp;as compared to the conventional&amp;nbsp;&lt;em&gt;FET&lt;/em&gt;-based sensors. In the second stage of our investigation, we provide a performance assessment of the proposed phototransistor by analyzing its switching capabilities as compared to the conventional design, where the device is implemented in an optical&amp;nbsp;inverter&amp;nbsp;circuit. The obtained results indicate the superior optoelectronic performance offered by the proposed design in comparison with the conventional devices in terms of optical commutation speed and optoelectronic gain. Therefore, this contribution can provide new insights concerning the benefit of adopting&amp;nbsp;&lt;em&gt;JL-TFET&lt;/em&gt;&amp;nbsp;design for future high-performance and ultra-low power deep submicron CMOS optoelectronic applications.

	Pb0 centers are the main defects at the Si(100)/SiO&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;interface in conventional MOS transistors. Besides, the charge pumping (CP) technique in which a MOSFET is repeatedly switched between inversion and accumulation has been widely used for studying single capture/emission events in deep submicron transistors. In CP, the minority carriers stored into interface traps in inversion recombine in accumulation with majority carriers from the substrate (n-channel case). This provides a CP current which can be studied. When it was accepted that in submicron MOSFETs the CP current was given by Icp = f.q.N, where f is the gate signal frequency, q the electron charge, N the number of traps entering Icp, recently, Tsuchiya and co-workers, pointed out steps heights equal to 2.q: Pb0 centers with their donor-like and acceptor-like states in the lower and upper halves of the silicon bandgap, respectively were therefore measured for the first time in submicron devices. In the present paper, the traps remaining electrically active at the Si(100)-SiO&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;interface in large area conventional MOSFETs after the full technological process including forming gas annealing are studied. This is achieved using techniques developed in recent years that use the variation of the gate signal frequency for different gate voltage swings. The trap time constant distributions that exist at this interface are studied as function of gate voltage and gate signal frequency. The results are discussed with regard to the CP models previously proposed and to CP curves simulation.

	The present research letter is dedicated to a detailed analysis of a double-gate tunnel field-effect transistor (DG-TFET). The DG-TFET provides improved on-current (ION) than a conventional TFET via bandto-band (B2B) tunneling. However, DG-TFET is disadvantageous for low-power applications because of increased off-current (IOFF) due to the large ambipolar current (Iamb). In this research work, a Si/GaAs/ GaAs heterostructure DG-TFET is considered as research base for investigation of device performance. The electrical parameters of the DG-TFET device have been improved in comparison to the homostructure. The transfer (I-V) characteristics, capacitance - voltage (C-V) characteristic of homo structure Si/ Si/Si and hetero structure Si/GaAs/GaAs, DG-TFET both structures is analysed comparatively. The C-V characteristics of DG-TFET have obtained using operating frequency of 1 MHz. The ambipolar current Iamb is suppressed by 5 × 108 order of magnitude in proposed Si/GaAs/GaAs hetero DG-TFET as compared to Si/Si/Si homo DG-TFET up to the applied drain voltage very low equal to VDS = 0.5 V without affecting on- state performance. The simulation result shows a very good ION/IOFF ratio (1013) and low subthreshold slope, SS (~36.52 mV/dec). The various electrical characteristics of homo and hetero DGTFET such as on-current (ION), off - current (IOFF), time delay (ιd ), transconductance (gm) , and power delay product (PDP) have been improve in Si/GaAs/GaAs heterostructure DG-TFET and compared with Si/Si/ Si homo DG-TFET. The advantageous results obtained for the proposed design show its usability in the field of digital and analog applications.

	Dopant diffusion in semiconductors is a very important in process step of device. diffusion has a great influence on the electrical and electronic properties especially in the lacunary and interstitial mechanismis. This chapter investigates the diffusion of P and B in Si. The profiles have been simulated using Secondary Ion Mass Spectrometry (SIMS) modele [1,2]. In the process for manufacturing MOS transistor, the manufacturers follow basically three steps. The starting substrate is a monocrystalline silicon wafer. The first step consists in producing the polysilicon gate on a thin layer of SiO2 followed by implantation (boron) of the gate. The second step is the training of source-drain junctions by ion implantation to high dose (≈ 10 15 at / cm2) and the third is to silicide the source-drain junctions for reduce the contact resistance. One of the most promising silicides is the monosilicide of nickel (NiSi). therefore, it is very important to understand the redistribution of dopants in the different active parts of a transistor by studying the following points: • The redistribution of boron in polycrystalline silicon (gate), • The redistribution of boron in the monocrystal

	In this paper, we propose a new numerical method for acoustics microwaves detection of an acoustics microwaves signal during the propagation of acoustics microwaves in a piezoelectric substrate Zinc oxide (ZnO) . We have used Support Vector Machines (SVM) ,the originality of this method is the accurate values that provides .this technic help us to identify undetectable waves that we can not identify with the classical methods; in which we classify all the values of the real part and the imaginary part of the coefficient attenuation with the acoustic velocity in order to build a model from which we note the types of microwaves acoustics( bulk waves or surface waves or leaky waves) . By which we obtain accurate values for each of the coefficient attenuation and acoustic velocity. This study will be very interesting in modeling and realization of acoustics microwaves devices (ultrasound ,Radiating structures , Filter SAW ….) based on the propagation of acoustics microwaves.

	In this paper, Ni/NiO/Ni multilayers are deposited on glass substrates using radio frequency magnetron sputtering, where the structural and morphological properties are analyzed using X-ray diffraction besides scanning electron microscopy techniques. The associated magnetic hysteresis loops are obtained by vibrating sample magnetometer for temperatures ranging from − 100 to 300 °C. Hence, the parameters α, β, Bmax, HC, and Br defining a hysteresis loop are determined at each temperature using Preisach model for the first two parameters, while the remaining ones are deduced experimentally. The set of these parameters are introduced within the training data set in the context of an ANFIS-based approach to predict the hysteresis loop of a Ni/NiO/Ni multilayer for any temperature below the Curie temperature. The comparison conducted between theoretical and experimental results showed a good agreement. This work provided more insights regarding the consolidation of experimental characterization with the development of soft computing-based frameworks.

The electronic bang gap thermal dependence reveals a normal monotonic decrease in the SiC and GeC semiconductors, whereas SnC exhibits an anomalous behavior. The electron line widths were evaluated and the contributions of acoustic and optical phonon modes to the imaginary part of the self-energy were determined. It has been found that the e–ph scattering rates are globally controlled by the out-of-plane acoustic transverse mode ZA in SiC while both ZA and ZO are overriding in GeC. In SnC, the out-of-plane transverse optical mode ZO is the most dominant. The relaxation lifetime of the photo-excited electrons shows that the thermalization of the hot carrier occurs at 90 fs, 100 fs and 120 fs in SiC, GeC and SnC, respectively. The present study properly describes the subpicosecond time scale after sunlight illumination using an approach that requires no empirical data. The results make the investigated structures suitable for providing low cost and high-performance optical communication and monitoring applications using 2D materials.</style></abstract><issue><style face="normal" font="default" size="100%">N°13</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Kalinka Kacha</style></author><author><style face="normal" font="default" size="100%">Bendjerad, Adel</style></author><author><style face="normal" font="default" size="100%">Benhaya, Abdelhamid</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Influence of TCO intermediate thin-layers on the electrical and thermal properties of metal/TCO/p-Si Schottky structure fabricated via RF magnetron sputtering</style></title><secondary-title><style face="normal" font="default" size="100%">Physica E: Low-dimensional Systems and Nanostructures</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/pii/S1386947718313754</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">106</style></volume><pages><style face="normal" font="default" size="100%">25-30</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this paper, versatile&amp;nbsp;&lt;em&gt;Metal/TCO/p-Si&lt;/em&gt;&amp;nbsp;Schottky Barrier&amp;nbsp;Diodes (&lt;em&gt;SBDs&lt;/em&gt;) with dissimilar&amp;nbsp;&lt;em&gt;TCO&lt;/em&gt;&amp;nbsp;intermediate layers (&lt;em&gt;ZnO&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;ITO&lt;/em&gt;) were fabricated by&amp;nbsp;&lt;em&gt;RF&lt;/em&gt;&amp;nbsp;magnetron sputtering&amp;nbsp;technique. An overall electrical performance comparison between the&amp;nbsp;&lt;em&gt;Al/ZnO/p-Si, Au/ITO/p-Si&lt;/em&gt;&amp;nbsp;and the conventional&amp;nbsp;&lt;em&gt;Au/p-Si&lt;/em&gt;&amp;nbsp;structures is carried out. The measured&amp;nbsp;&lt;em&gt;I-V&lt;/em&gt;&amp;nbsp;characteristics indicate that the proposed&amp;nbsp;&lt;em&gt;Al/ZnO/p-Si&lt;/em&gt;&amp;nbsp;design exhibits an outstanding capability for achieving a high rectifying ratio of 142 dB. This is mainly due to the enhanced Schottky barrier height (&lt;em&gt;SBH&lt;/em&gt;) of&amp;nbsp;&lt;em&gt;0.&lt;/em&gt;75 V and close to unite ideality factor (&lt;em&gt;n&lt;/em&gt; = &lt;em&gt;1.23&lt;/em&gt;). Such behavior can be attributed to the enhanced interface quality achieved by introducing&amp;nbsp;&lt;em&gt;TCO&lt;/em&gt;&amp;nbsp;inter-layers, which could decrease the Series resistance. A comparative study of the elaborated structures performance is carried out in which new Figures of Merit (&lt;em&gt;FoM&lt;/em&gt;) parameters that combine both electrical and thermal stability performances are proposed. The Experimental results show that the proposed designs with&amp;nbsp;&lt;em&gt;ITO&lt;/em&gt;&amp;nbsp;and&amp;nbsp;&lt;em&gt;ZnO&lt;/em&gt;&amp;nbsp;sub-layers exhibits improved&amp;nbsp;&lt;em&gt;FoM&lt;/em&gt;&amp;nbsp;parameters as compared to the conventional&amp;nbsp;&lt;em&gt;Au/p-Si&lt;/em&gt;&amp;nbsp;structure.

It is demonstrated that the insertion of a&amp;nbsp;&lt;em&gt;TCO&lt;/em&gt;&amp;nbsp;inter-layer might be beneficial for avoiding the degradation related-heating effects. Therefore, the proposed designs offer the possibility of bridging the gap between superior electrical performance and high thermal stability, which makes them suitable for developing high-performance Schottky solar cells and sensing applications.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Benhaya, Abdelhamid</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Optimized high-performance ITO/Ag/ITO multilayer transparent electrode deposited by RF magnetron sputtering</style></title><secondary-title><style face="normal" font="default" size="100%">Superlattices and Microstructures</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/abs/pii/S0749603619304835</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">129</style></volume><pages><style face="normal" font="default" size="100%">176-184</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper presents the optimization, elaboration and characterization of a new&amp;nbsp;&lt;em&gt;TCO&lt;/em&gt;&amp;nbsp;(Transparent Conductive Oxides)&amp;nbsp;electrode&amp;nbsp;based on&amp;nbsp;&lt;em&gt;ITO/Ag/ITO&lt;/em&gt;&amp;nbsp;multilayer design that enables overcoming the trade-off between the electrical and optical properties. A new hybrid approach combining the investigated design and Particle Swarm Optimization (&lt;em&gt;PSO&lt;/em&gt;) technique is conducted with the aim of maximizing the&amp;nbsp;&lt;em&gt;Haacke&lt;/em&gt;&amp;nbsp;Figures of merit (&lt;em&gt;FoM&lt;/em&gt;).

Such improvement is attributed to the improved light management achieved by the efficient modulation of the&amp;nbsp;&lt;em&gt;Ag&lt;/em&gt;&amp;nbsp;sub-layer geometry. Subsequently, the optimized multilayer design is fabricated using&amp;nbsp;&lt;em&gt;RF&lt;/em&gt;&amp;nbsp;magnetron sputtering&amp;nbsp;technique. The structural, optical and electrical properties associated with the deposited&amp;nbsp;&lt;em&gt;ITO/Ag/ITO&lt;/em&gt;&amp;nbsp;multilayer structure&amp;nbsp;are also analyzed.

The proposed tandem design consists of a&amp;nbsp;&lt;em&gt;Se&lt;/em&gt;-based top cell with&amp;nbsp;&lt;em&gt;Ti&lt;/em&gt;&amp;nbsp;intermediate ultra-thin metallic layers (&lt;em&gt;MLs&lt;/em&gt;) and a&amp;nbsp;&lt;em&gt;CZTS&lt;/em&gt;&amp;nbsp;bottom cell with graded band-gap aspect.

	In this paper, a transparent conductive&amp;nbsp;&lt;em&gt;ITO/Ag/ITO&lt;/em&gt;&amp;nbsp;(&lt;em&gt;IAI&lt;/em&gt;) multilayer structure with a high Haacke Figure of Merit (&lt;em&gt;FoM&lt;/em&gt;) far surpassing those found up to now is experimentally demonstrated. An optimized&amp;nbsp;&lt;em&gt;IAI&lt;/em&gt;&amp;nbsp;multilayer electrode was elaborated by means of&amp;nbsp;&lt;em&gt;RF&lt;/em&gt;&amp;nbsp;magnetron sputtering technique. The structural and electrical characteristics of the prepared tri-layered design were investigated. The influence of the annealing process on the&amp;nbsp;&lt;em&gt;IAI&lt;/em&gt;&amp;nbsp;electrode performance was also carried out. Unlike the&amp;nbsp;&lt;em&gt;IAI&lt;/em&gt;&amp;nbsp;structure as-deposited, it was revealed that the annealed samples maintained an average transparency superior than&amp;nbsp;&lt;em&gt;89%&lt;/em&gt;. This behavior indicates the effectiveness of the thermal treatment for ensuring favorable light management. In addition, it was found that the annealing process paves a new path toward improving the electrode conductivity, where the heat treated electrode at&amp;nbsp;&lt;em&gt;600°C&lt;/em&gt;&amp;nbsp;yielded a very low sheet resistance of&amp;nbsp;&lt;em&gt;2.95Ω&lt;/em&gt; × &lt;em&gt;sq&lt;/em&gt;&lt;sup&gt;&lt;em&gt;−1&lt;/em&gt;&lt;/sup&gt;. Therefore, by well optimizing both&amp;nbsp;&lt;em&gt;IAI&lt;/em&gt;&amp;nbsp;geometry and annealing conditions, we were able to elaborate high-quality coating with a superior&amp;nbsp;&lt;em&gt;FoM&lt;/em&gt;&amp;nbsp;of&amp;nbsp;&lt;em&gt;120.8&lt;/em&gt; × &lt;em&gt;10&lt;/em&gt;&lt;sup&gt;&lt;em&gt;−3&lt;/em&gt;&lt;/sup&gt;&lt;em&gt;Ω&lt;/em&gt;&lt;sup&gt;&lt;em&gt;−1&lt;/em&gt;&lt;/sup&gt;. This makes the sputtered&amp;nbsp;&lt;em&gt;IAI&lt;/em&gt;&amp;nbsp;multilayer design a suitable alternative to the conventional&amp;nbsp;&lt;em&gt;ITO&lt;/em&gt;-based electrodes for optoelectronic and photovoltaic applications.

	This paper presents an efficient method for recovery of SIMS signals from strongly noised blurred discrete data. This technique is based on Tikhonov-Miller regularization where a priori model of solution is included. The latter is a denoisy signal obtained using the Kalman filter. This is an interesting estimation method, but it can only be used when the system is described precisely. By comparing the results of the proposed technique with those of the literature, our algorithm gives the best results without artifacts and oscillations related to noise and significant improvement of the depth resolution. While, the gain in FWHM is less improved than those obtained by the wavelet technique. Therefore, this new algorithm can push the limits of SIMS measurements towards its ultimate resolution.

	Our work is mainly about detecting acoustics microwaves in the type of BAW (Bulk acoustic waves), where we compared between Lithium Niobate (LiNbO3) and Lithium Tantalate (LiTaO3) ,during the propagation of acoustic microwaves in a piezoelectric substrate. In this paper, We have used the classification by Probabilistic Neural Network (PNN) as a means of numerical analysis in which we classify all the values of the real part and the imaginary part of the coefficient attenuation with the acoustic velocity for conclude whichever is the best in utilization for generating bulk acoustic waves.This study will be very interesting in modeling and realization of acoustic microwaves devices (ultrasound) based on the propagation of acoustic microwaves.

		In this paper, new expressions for the effective radius and fringing capacitance have been derived to predict accurately the resonant frequency of the two-layered circular microstrip patch antenna. These expressions are obtained based on genetic algorithm and the data base is generated using moment method (MOM). The proposed model is very simple, fast, and valid for an entire range of permittivities and thicknesses of two-layered substrate. The present model has been validated by comparing our numerical results obtained for the resonant frequencies with measurements. Finaly, the effect of the two-layered substrate on the resonant charateristics of the circular microstrip patch antenna has been presented.

	The resonant frequencies and bandwidths of the inverted rectangular patch over anisotropic substrates are investigated in this paper. A rigorous analysis is performed using dyadic Green’s function formulation in the vector Fourier transform domain. The Galerkin’s technic is then used in the resolution of the integral equation; the complex resonance frequencies for the TM01 mode are studied with sinusoidal basis functions. The numerical results obtained are compared with previously published numerical results computed by means of the electromagnetic simulator “IE3D software”. Good agreement is found in all cases among all sets of results. For an isotropic substrate, it is confirmed that the bandwidth decreases with increasing of air-gap layer for high permittivity and low thickness of the substrate. Also, we show that the resonant frequencies and bandwidths are highly dependent on the permittivity variations alongside the optical axis. Other theoretical results attained display that the resonant frequencies downtrend monotonically with increasing substrate thickness, the diminution being larger for the uniaxial anisotropy of the substrate. Finally, numerical results for the effects of uniaxial anisotropy in the substrate on the radiation of the inverted rectangular microstrip structure are also presented.

In this paper, we used a chemical sensor array to develop an electronic nose to detect and identify seven different gases (H&lt;sub&gt;2&lt;/sub&gt;, C&lt;sub&gt;2&lt;/sub&gt;H&lt;sub&gt;2&lt;/sub&gt;, CH&lt;sub&gt;4&lt;/sub&gt;, CH&lt;sub&gt;3&lt;/sub&gt;OCH&lt;sub&gt;3&lt;/sub&gt;, CO, NO&lt;sub&gt;2&lt;/sub&gt;, and NH&lt;sub&gt;3&lt;/sub&gt;). These gas sensors are chosen because of its hierarchical/doped nanostructure characteristics, which give them a very high sensitivity and low response time; we improve the linearity response and temperature dependence using models based on artificial neural networks. We used in Electronic nose a pattern recognition based on artificial neural network, which discriminates qualitatively and quantitatively seven gases and has a fast response.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bentrcia Toufik</style></author><author><style face="normal" font="default" size="100%">Djeffal Fayçal</style></author><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Dibi Zohir</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A Comparative Study on Scaling Capabilities of Si and SiGe Nanoscale Double Gate Tunneling FETs ISSN / e-ISSN 1876-990X / 1876- 9918</style></title><secondary-title><style face="normal" font="default" size="100%">Silicon-Neth</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://link.springer.com/article/10.1007/s12633-019-00190-w</style></url></web-urls></urls><pages><style face="normal" font="default" size="100%">pp 1–9</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the last few years, an accelerated trend towards the miniaturization of nanoscale circuits has been recorded. In this context, the Tunneling Field-Effect Transistors (TFETs) are gaining attention because of their good subthreshold characteristics, high scalability and low leakage current. However, they suffer from low values of the ON-state current and severe ambipolar transport mechanism. The aim of this work is to investigate the performance of SiGe nanoscale Double Gate TFET device including low doped drain region. The electrical performance of the considered device is investigated numerically using ATLAS 2D simulator, where both scaling and reliability aspects of the proposed design are reported. In this context, we address the impact of the channel length, traps density and drain doping parameters on the variation of some figures of merit of the device namely the swing factor and the I&lt;sub&gt;ON&lt;/sub&gt;/I&lt;sub&gt;OFF&lt;/sub&gt;&amp;nbsp;ratio. The obtained results indicate the superior immunity of the proposed design against traps induced degradation in comparison to the conventional TFET structure. Therefore, this work can offer more insights regarding the benefit of adopting channel materials and drain doping engineering techniques for future reliable low-power nanoscale electronic applications.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bendjerad, Adel</style></author><author><style face="normal" font="default" size="100%">Benhaya, Abdelhamid</style></author><author><style face="normal" font="default" size="100%">Bentercia, Toufik</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Zergoug, M</style></author><author><style face="normal" font="default" size="100%">Smaili, F</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Determination of magnetic properties of a Ni/NiO/Ni multilayer: an ANFIS-based predictive technique</style></title><secondary-title><style face="normal" font="default" size="100%">Applied Physics </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2019</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://link.springer.com/article/10.1007/s00339-018-2349-z</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">125</style></volume><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	In this paper, Ni/NiO/Ni multilayers are deposited on glass substrates using radio frequency magnetron sputtering, where the structural and morphological properties are analyzed using X-ray diffraction besides scanning electron microscopy techniques. The associated magnetic hysteresis loops are obtained by vibrating sample magnetometer for temperatures ranging from − 100 to 300&amp;nbsp;°C. Hence, the parameters&amp;nbsp;&lt;i&gt;α, β, B&lt;/i&gt;&lt;sub&gt;max&lt;/sub&gt;,&amp;nbsp;&lt;i&gt;H&lt;/i&gt;&lt;sub&gt;C&lt;/sub&gt;, and&amp;nbsp;&lt;i&gt;B&lt;/i&gt;&lt;sub&gt;r&lt;/sub&gt;&amp;nbsp;defining a hysteresis loop are determined at each temperature using Preisach model for the first two parameters, while the remaining ones are deduced experimentally. The set of these parameters are introduced within the training data set in the context of an ANFIS-based approach to predict the hysteresis loop of a Ni/NiO/Ni multilayer for any temperature below the Curie temperature. The comparison conducted between theoretical and experimental results showed a good agreement. This work provided more insights regarding the consolidation of experimental characterization with the development of soft computing-based frameworks.

	La miniaturisation des dimensions du transistor était le facteur principal et le plus important menant aux améliorations des performances et du coût du circuit intégré contribuant au développement rapide de l'industrie des semi-conducteurs. Dans cette thèse, nous proposons tout d'abord une nouvelle structure MOSFET à double grille sans jonction (DGJL) basée à la fois sur la grille double matériaux et les extensions fortement dopées liées aux drain et source. Des modèles analytiques associés au courant de drain, aux paramètres de performance analogique et radiofréquence (RF) sont développés en incorporant l'impact d'une grille à deux matériaux et deux régions d'extension fortement dopées sur les performances analogique/RF du MOSFET DGJL. Les facteurs de mérite (FOM) du transistor, qui régissent le comportement analogique/RF, sont également analysées. Les résultats de notre étude concernant les performances analogique/RF pour la structure proposée sont discutés et comparés avec ceux d‟un MOSFET DGJL conventionnel de dimensions similaires, où le dispositif proposé présente une excellente capacité à améliorer ces performances, et fournit un courant de drain plus élevé. Les résultats délivrés sont validés par rapport aux données obtenues à partir du logiciel TCAD pour une large gamme de paramètres de conception. De plus, les modèles analytiques développés ont été adoptés comme une fonction objectif pour optimiser les performances analogique/RF du dispositif en utilisant les Algorithmes Génétiques (AGs). En comparaison avec les données numériques rapportées pour la structure MOSFET en mode d‟Inversion (IM), nos paramètres de performance optimisés pour le dispositif JL présentent une amélioration en comparaison avec le dispositif en mode d'inversion. Cette thèse s‟occupe également de l'immunité du dispositif DG MOSFET sans jonctions envers l'effet de dégradation initié par les porteurs chauds. En conséquence, nous avons démontré que le DG MOSFET sans jonctions peut être un choix fiable pour améliorer les performances relatives aux transistors MOSFET à l'échelle nanométrique pour les applications numériques.

	L’objectif de cette thèse est l’analyse des antennes microrubans fabriquées à base de patchs parfaitement conducteurs et supraconducteurs avec et sans couche protectrice utilisant deux méthodes différentes : le modèle de la cavité basé sur les connaissances électromagnétiques et l’approche spectrale conjointement avec les conditions aux limites de la résistivité complexe. La première méthode est choisie puisque, contrairement aux méthodes rigoureuses, elle fournit une compréhension qualitative en plus de requérir des développements mathématiques relativement courts. La deuxième méthode est réservée à l’étude des caractéristiques de résonance d’un patch microbande circulaire supraconducteur à haute température critique avec une couche protectrice. Des résultats numériques sont présentés pour le mode fondamental aussi bien que pour les modes d’ordre supérieur. Une étude paramétrique est menée pour quantifier l’influence de certains paramètres électriques et physiques sur les performances de l’antenne en tenant compte de l’anisotropie uniaxiale dans le diélectrique. Les résultats numériques de chaque structure sont comparés aux données théoriques et expérimentales reportées dans la littérature ouverte.

	Les onduleurs sont des convertisseurs DC-AC de plus en plus utilisés dans les systèmes énergétiques, en particulier dans les énergies renouvelables. Pour cela, les onduleurs doivent utiliser l'énergie disponible de manière efficace. Ils doivent donc avoir une efficacité et une fiabilité élevées. De plus, les performances de ces systèmes sont mesurées par leur efficacité, forme d'onde et distorsion harmonique de la sortie, et enfin leur coût, qui dépendent du choix optimal des composants et de la stratégie de contrôle. Dans cette thèse, nous étudierons certaines structures et stratégies de contrôle, en nous concentrant davantage sur la réduction de la distorsion harmonique totale (THD). La réduction du THD dans les inverseurs multiniveaux nécessite la résolution d'équations transcendantales non linéaires complexes. Sans avoir à résoudre ces équations, nous avons proposé d'utiliser le récent algorithme firefly (FFA) pour optimiser le THD, en trouvant les meilleurs angles de commutation et en garantissant la minimisation des harmoniques dans une bande passante prédéfinie par l'utilisateur. Le FFA a été comparé à certains algorithmes largement utilisés existants tels que l'algorithme génétique (GA), et a montré une convergence plus rapide. Nous avons également choisi d'utiliser l'une des meilleures structures matérielles optimisées existantes, où nous avons validé les résultats de la simulation par des tests pratiques. Nous insistons sur le fait que la meilleure conception seule ou la meilleure stratégie de contrôle seule ne peut pas résoudre le problème THD à un coût raisonnable. Il est impératif d'aborder les deux sujets en même temps. La THD obtenu grâce à la simulation de l'onduleur symétrique de treize niveaux a été réduite à 5% (FFT de 60 harmoniques). Afin de valider les résultats de la simulation, un prototype d'onduleur symétrique de treize niveaux a été réalisé et pratiquement expérimenté et testé avec différentes charges. Par conséquent, la THD mesurée avec une charge résistive était de 4,7% sur une bande passante de 3 kHz.

	The article introduces the benefits and application features of Silvaco Technology Computer Aided Design‘TCAD’ tool to predict the performance of electrical components and their reliability. In this work, in order to improve the electrical parameters of MOS transistor such as, threshold voltage and flat band voltage, we have simulated Phosphorus and Arsenic diffusion profiles in three dimensions before and after thermal annealing in a highly doped polysilicon film using the simulator Silvaco TCAD based on Pearson type IV models. The model takes into account the distribution of vacancy mechanisms and effects related to high concentrations, such as the formation of clusters to study solid solubility limit. The results have been analyzed and discussed in order to extract depth of doping (Phosphorus and Arsenic) and they have been able to optimize the silicon oxide thickness, to reduce the penetration of doping. Based on earlier studies a study of the effect of solubility on these profiles was performed

	In this paper we have developed an algorithm of boron diffusion after thermal annealing in a highly doped polysilicon film. This algorithm takes into account electrically active point defects by associating some parameters such as boron solubility limit and diffusion coefficient. We have studied effect of annealing temperature in order to perform impact of this parameter on maximum depth diffusion of junction and maximum of concentration by analysis of Secondary Ion Mass Spectrometry (SIMS) profiles. In fact we have proposed numerical model based on Fick's equation, resolved by finite difference method under Matlab also we have simulated this phenomenon by Silvaco software.

		&lt;span&gt;&lt;span&gt;In this paper, graded Ge &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/mole-fraction&quot; title=&quot;Learn more about Mole Fraction from ScienceDirect's AI-generated Topic Pages&quot;&gt;mole fraction&lt;/a&gt;&lt;span&gt;&lt;span&gt; aspect is proposed as a new way to achieve the dual benefit of improved Si/SiGe-based solar cell photoconversion efficiency and suppressed degradation related-dislocation effects. Our purpose resides mainly on decreasing the &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/defect-density&quot; title=&quot;Learn more about Defect Density from ScienceDirect's AI-generated Topic Pages&quot;&gt;defect density&lt;/a&gt; at the Si/SiGe interface through shifting the &lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/ge-concentration&quot; title=&quot;Learn more about Ge Concentration from ScienceDirect's AI-generated Topic Pages&quot;&gt;Ge concentration&lt;/a&gt;&lt;span&gt; gradually with the SiGe &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/absorber-layer&quot; title=&quot;Learn more about Absorber Layer from ScienceDirect's AI-generated Topic Pages&quot;&gt;absorber layer&lt;/a&gt; thickness. Further, a careful mechanism analysis based on investigating numerically the impact of the proposed graded Ge content paradigm on reducing the degradation related-dislocation effect is performed. The advantage of using a SiGe layer with graded Ge concentration instead of a thin-film SiGe alloys is presented. Moreover, the impact of the proposed SiGe layer thickness on the solar cell conversion efficiency is carried out. It is found that the proposed feature brings the opportunity of reducing the &lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/lattice-mismatch&quot; title=&quot;Learn more about Lattice Mismatch from ScienceDirect's AI-generated Topic Pages&quot;&gt;lattice mismatch&lt;/a&gt; at the Si/SiGe interface, which can in turn improve the Si/SiGe-based solar cell conversion efficiency. In addition, increasing the Ge content progressively suggests the band-gap modulation aspect that enables improving the solar cell &lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/electromagnetic-absorption&quot; title=&quot;Learn more about Electromagnetic Absorption from ScienceDirect's AI-generated Topic Pages&quot;&gt;optical absorption&lt;/a&gt;&lt;span&gt; and the total resistance.

		&lt;span&gt;&lt;span&gt;&lt;span&gt;In this paper, we propose a new n-ZnO/p-Si hetero-junction solar cell design based on both interface engineering and &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/metallic-nanoparticles&quot; title=&quot;Learn more about Metallic Nanoparticles from ScienceDirect's AI-generated Topic Pages&quot;&gt;metallic nanoparticles&lt;/a&gt;&lt;span&gt; aspects. The merits of using both metallic nanoparticles and grooves morphology in the ZnO/p-Si interface to improve solar cell optical performance are investigated numerically using accurate solutions of Maxwell’s equations. It is found that the proposed structure suggests the possibility to achieve the dual role of improved light-scattering in the Si &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/absorber-layer&quot; title=&quot;Learn more about Absorber Layer from ScienceDirect's AI-generated Topic Pages&quot;&gt;absorber layer&lt;/a&gt; as well as enhancing the absorption in the ZnO thin-film through the &lt;/span&gt;&lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/surface-plasmon&quot; title=&quot;Learn more about Surface Plasmon from ScienceDirect's AI-generated Topic Pages&quot;&gt;Surface Plasmon&lt;/a&gt; Resonance effect. Besides, the proposed design exhibits superior optical performance and offers improved total absorbance efficiency (TAE) as compared to the conventional counterpart. Moreover, &lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/particle-swarm-optimization&quot; title=&quot;Learn more about Particle Swarm Optimization from ScienceDirect's AI-generated Topic Pages&quot;&gt;particle swarm optimization&lt;/a&gt; (&lt;/span&gt;&lt;em&gt;PSO&lt;/em&gt;&lt;span&gt;&lt;span&gt;)-based approach is exploited for the &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/geometrical-optimization&quot; title=&quot;Learn more about Geometrical Optimization from ScienceDirect's AI-generated Topic Pages&quot;&gt;geometrical optimization&lt;/a&gt;&lt;span&gt; of the proposed design to achieve higher light trapping capability.

The idea behind this work is to generate optical confinement regions in the &lt;i&gt;CZTS&lt;/i&gt; absorber layer to achieve an improved absorption and appropriate antireflection effects. Moreover, the ultra-thin metal at the &lt;i&gt;CZTS&lt;/i&gt;/&lt;i&gt;Mo&lt;/i&gt; interface can be helpful for reducing the series resistance, where it behaves like a blocking layer for the Sulfur diffusion. We further combine the proposed designs with Particle Swarm Optimization (&lt;i&gt;PSO&lt;/i&gt;)-based approach to achieve broadband absorption and boost the conversion efficiency.

The amended channel doping consists of a lateral graded profile, where the channel is divided into two regions with different doping levels. Analytical approaches for the drain current, leakage power, digital and small signal parameters are developed incorporating the impact of graded channel doping (&lt;i&gt;GCD&lt;/i&gt;) paradigm on the device electrical behavior.

The impact of different band-gap profiles on the phototransistor figure of merits (FoMs) is analyzed. Our study demonstrates that the use of ZnMgO with a graded band-gap profile can generate an electric field in the photosensitive layer, which leads to achieve the dual role of effective electron/hole pair separation and lower recombination losses. Moreover, increasing the Mg content progressively not only enables a strong UV-light absorption but also allows achieving a high optical sensitivity for very low optical powers (sub-1pW). The particle-swarm optimization approach is exploited to boost the phototransistor FoMs by optimizing the sensor design parameters and the ZnMgO band-gap profile. It is found that the optimized structure exhibits superior optical characteristics as compared to those of the conventional UV-photodetectors. Therefore, the optimized ZnMgO UV-OCFET with graded band-gap paradigm pinpoints a new path toward recording an ultrasensitive phototransistor compatible with CMOS modern technology. This makes it a potential alternative for high-performance and low-energy consumption chip-level UV-communication and monitoring applications.</style></abstract><issue><style face="normal" font="default" size="100%"> Issue 3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Benhaya, Abdelhamid</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Kalinka Kacha</style></author><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Bendjerad, Adel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Role of ITO ultra-thin layer in improving electrical performance and thermal reliability of Au/ITO/Si/Au structure: An experimental investigation, ISSN 0749-6036</style></title><secondary-title><style face="normal" font="default" size="100%">Superlattices and Microstructures</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/325553017_Role_of_ITO_ultra-thin_layer_in_improving_electrical_performance_and_thermal_reliability_of_AuITOSiAu_structure_An_experimental_investigation</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">120</style></volume><pages><style face="normal" font="default" size="100%">419-426 </style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	In this paper, the role of introducing an intermediate Indium Tin Oxide (ITO) thin-film in improving the Au/Si Schottky Barrier Diodes (SBDs) electrical performance is experimentally analyzed. The Au/ITO/Si/Au structures with different ITO thicknesses were fabricated using RF magnetron sputtering technique. The current-voltage (I-V) characteristics of the investigated structures are analyzed, where the device electrical parameters are extracted. It is found that the introduced ITO thin-film has a significant impact in reducing the ideality factor (n=1.25), the interfacial defects (Nss=1.5×1012 eV−1cm−2) and the series resistance (Rs=32Ω). Our study demonstrates that the use of ITO intermediate thin-film can generate minority carrier injection effects, which lead to achieve the dual role of enhanced derived current and lower series resistance. Moreover, the structure thermal stability behavior is investigated and compared with those of the conventional design in order to reveal the device reliability against the thermal variation. Furthermore, the effect of the annealing on the device thermal stability is also analyzed. Our investigation shows that the annealed structure provides the possibility for avoiding the degradation related-heating effects. Therefore, the proposed Au/ITO/Si/Au structure offers the opportunity for bridging the gap between achieving superior electrical performance and enhanced thermal stability. The obtained results may facilitate the design of high-performance SBDs for sensing and microelectronic applications.

The new results found indicate that, the lower resonant frequency is mainly determined by the patch etched on the thicker layer. The layer having the higher permittivity defines which resonance is mainly determined by the bottom patch, either the upper resonance if the upper layer has the higher permittivity, or the lower resonance in opposite case.

					In this paper, the resonant frequencies, quality factors and bandwidths of high &lt;span class=&quot;italic&quot;&gt;T&lt;/span&gt;&lt;span class=&quot;sub&quot;&gt;c&lt;/span&gt; superconducting circular microstrip patches in the presence of a dielectric superstrate loading have been studied using Galerkin testing procedure in the Hankel transform domain. The exact Green's function of the grounded dielectric slab is used to derive an electric field integral equation for the unknown current distribution on the circular disc. Thus, surface waves, as well as space wave radiation, are included in the formulation. London's equations and the two-fluid model of Gorter and Casimir are used in the calculation of the complex surface impedance of the superconducting circular disc. Galerkin testing is used in the resolution of the electric field integral equation. Two solutions using two different basis sets to expand the unknown disk currents are developed. The first set of basis functions used is the complete set of transverse magnetic and transverse electric modes of a cylindrical cavity with magnetic side walls. The second set of basis functions used employ Chebyshev polynomials and enforce the current edge condition. The computed values for a wide range of variations of superstrate thickness and dielectric constant are compared with different theoretical and experimental values available in the open literature, showing close agreement. Results are showing that the superstrate parameters should always be kept into account in the design stage of the superconducting microstrip resonators.

Detailed analytical expressions of the dyadic Green’s functions are derived. Galerkin’s procedure is applied to solve the electric field integral equations, and the resonance characteristics are determined by solving the characteristic equation. Numerical results show that the influence of the magnetic anisotropy on the resonant frequencies is highly dependent on the permeability of the medium, where for a non-magnetic medium, the impact of the existing anisotropy was found negligible. However, for a magnetic medium, the anisotropy has a large impact on the resonant frequencies. Moreover, the influence of each of the components of the permeability tensor has been also reported.</style></abstract><issue><style face="normal" font="default" size="100%">N°1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hafdaoui, Hichem</style></author><author><style face="normal" font="default" size="100%">Benatia, Djamel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A comparative study for two LiNbO3 cuts (Y-Z and Y-X) in detecting bulk acoustic microwaves using Probabilistic Neural Network</style></title><secondary-title><style face="normal" font="default" size="100%">Engineering Science and Technology, an International Journal</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/324125585_A_comparative_study_for_two_LiNbO3_cuts_Y-Z_and_Y-X_in_detecting_bulk_acoustic_microwaves_using_Probabilistic_Neural_Network</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">21</style></volume><pages><style face="normal" font="default" size="100%">527-531</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	This work is mainly on the detection of the bulk acoustic waves (BAWs), where we have compared two Lithium Niobate cuts (Y-Z and Y-X), during the propagation of the acoustic microwaves in the piezoelectric LiNbO3-substrate. In this paper, we have used the classification by Probabilistic Neural Network (PNN) as a tool for numerical analysis in which we classify all the values of the real and imaginary parts of the attenuation coefficient for the propagation velocity. This analysis can allow us to demonstrate the best possibility in utilization for the BAW generation. This study will be very interesting in modeling and realization of acoustic wave devices (ultrasound) based on the propagation of acoustic microwaves.

A new electro-thermal (ET) model of low voltage power MOSFET is described in this paper. The electro-thermal model allows fast estimation of the junction temperature, based on the transient thermal impedances (Zth) using the (RC) Foster thermal network model and total power losses. The parameters of the (RC) Foster thermal network model are extracted from the data provided by the manufacturer’s datasheet using particle swarm optimization (PSO) method. Moreover, a dc/dc Buck converter is also analyzed by simulation to evaluate the electro-thermal model. The simulation results indicate a good agreement between the proposed model and manufacturer’s data.

The proposed GAAJ MOSFET design includes highly extension regions doping. The aim is to investigate the impact of this design on the RF and analog performances systematically and to show the immunity behavior against the short channel effects (SCEs) degradation. In this context, an analytical model via the meticulous solution of 2D Poisson equation, incorporating source/drain (S/D) extensions effect, has been developed and verified by comparing it with TCAD simulation results. A comparative evaluation between the proposed GAAJ MOSFET structure and the classical device in terms of RF/Analog performances is also investigated. The proposed design provides RF/Analog performances improvement. Furthermore, based on the presented analytical models, Genetic Algorithms (GA) optimization approach is used to optimize the design of S/D parameters. The optimized structure exhibits better performances, i.e., cut-off frequency and drive current are improved. Besides, it shows superior immunity behavior against the RF/Analog degradation due to the unwanted SCEs. The insights offered by the proposed paradigm will help to enlighten designer in future challenges facing the GAAJ MOSFET technology for high RF/analog applications.</style></abstract><issue><style face="normal" font="default" size="100%">N°2</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">S.

The present paper proposes a new solution for gas sensor selectivity based on artificial neural networks (ANNs) and fuzzy logic (FL) algorithm. We first use ANNs to develop a gas sensor model in order to accurately express its behavior. In a second step, the FL and Matlab environment are used to create a database for a selective model, where the response of this one only depends on one chemical species. Analytical models for the gas sensor and its selective model are implemented into a Performance Simulation Program with Integrated Circuit Emphasis (PSPICE) simulator as an electrical circuit in order to prove the similarity of the analytical model output with that of the MQ-9 gas sensor where the output of the selective model only depends on one gas. Our results indicate the capability of the ANN-FL hybrid modeling for an accurate sensing analysis.</style></abstract><issue><style face="normal" font="default" size="100%">6</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Lakehal Brahim</style></author><author><style face="normal" font="default" size="100%">Dendouga Abdelghani</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Parameter Extraction of Schottky Solar Cell in Wide Temperature Range UsingGenetic Algorithms, ISSN / e-ISSN 2077-6772 / 2306-4277</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Nano- and Electronic Physics</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/329836321_Parameter_Extraction_of_Schottky_Solar_Cell_in_Wide_Temperature_Range_Using_Genetic_Algorithms</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">volume 10</style></volume><pages><style face="normal" font="default" size="100%">pp 06046-1 - 06046-4</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper proposes a new method based on a genetic algorithm (GA) approach to optimize the electrical parameters such as height barrier, ideality factor, fill factor, open-circuit voltage and power conversion efficiency, in order to improve the electrical performance of Schottky solar cells in an over wide range of temperature.

Afterwards, we have quantified seventy postural parameters, they were combined of linear stabilometric parameters and non-linear time dependent stochastic parameters using stabilogram diffusion analysis and some spectral attributes using power spectral density. The aim of our analysis is to reduce data dimensionality using principal component analysis (PCA). Furthermore, we proposed a new PCA-related criterion named: criterion of contribution in order to evaluate the contribution of every variable in the resulted system structure, and thus to eliminate the redundant postural characteristics. Afterwards, we highlighted some interesting distinctive parameters. The selected parameters were used thereafter in comparison between the studied groups. Finally, we created a classification model using support vector machines to distinguish stroke patients. Our proposed techniques help in understanding the human postural dynamics and facilitate the diagnosis of pathologies related to equilibrium which can be used to improve the rehabilitation services.</style></abstract><issue><style face="normal" font="default" size="100%"> Issue 1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hedjazi Naceur</style></author><author><style face="normal" font="default" size="100%">Benali Abderraouf</style></author><author><style face="normal" font="default" size="100%">Bouzit Mourad</style></author><author><style face="normal" font="default" size="100%">Dibi Zohir</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Model identification and evaluation of postural dynamics of healthy and post-stroke individuals under unidirectional perturbations, ISSN / e-ISSN 1746-8094 / 1746-8108</style></title><secondary-title><style face="normal" font="default" size="100%">Biomedical Signal Processing and Control</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/abs/pii/S1746809418300466</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Volume 43</style></volume><pages><style face="normal" font="default" size="100%">pp 75-85</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this paper, different techniques of analysis have been used to study the effects of perturbations generated from a&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/robotics&quot; title=&quot;Learn more about Robotics from ScienceDirect's AI-generated Topic Pages&quot;&gt;robotic&lt;/a&gt;&amp;nbsp;mobile platform called Isiskate. These disturbances were applied on two categories of people: post-CVA subjects suffering from cerebrovascular accident and healthy individuals. Our aim is to analyze some assessment tools to distinguish between different postural behaviors. In relevant works, very few studies have addressed the use of nonlinear time-series methods in diagnosis of post-CVA pathological postural behavior.

The combination of the proposed techniques has provided us an understanding of human control process by establishing a behavior model and helped us to distinguish patients with postural disorders. This improves postural analysis and facilitates the diagnosis of pathologies related to equilibrium which serves in rehabilitation.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">F.Menacer</style></author><author><style face="normal" font="default" size="100%">Dibi Zohir</style></author><author><style face="normal" font="default" size="100%">A.Kadri</style></author><author><style face="normal" font="default" size="100%">Djeffal Fayçal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">A new smart nanoforce sensor based on suspended gate SOIMOSFET using carbon nanotube ISSN / e-ISSN 0263-2241 / 1873- 412X</style></title><secondary-title><style face="normal" font="default" size="100%">Measurement</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/pii/S0263224118303452</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Volume 125</style></volume><pages><style face="normal" font="default" size="100%"> Pages 232-242</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">This paper presents a new nanoforce sensor based on a suspended carbon&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/nanotubes&quot; title=&quot;Learn more about Nanotubes from ScienceDirect's AI-generated Topic Pages&quot;&gt;nanotube&lt;/a&gt;&amp;nbsp;gate&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/field-effect-transistors&quot; title=&quot;Learn more about Field Effect Transistors from ScienceDirect's AI-generated Topic Pages&quot;&gt;field-effect transistor&lt;/a&gt;.

Based on the dielectric modulation effect, DNA molecules in the nanogap cavity change due to the charge density of biomolecules, producing a change in the threshold voltage of the device. Analytical and numerical analysis was carried out to reveal the impact of physical parameters on the sensitivity of the proposed biosensor. Various characteristics, such as the surface potential, threshold voltage, and drain current were also investigated. The effectiveness of the proposed TM-DG-DM-JL-MOSFET structure with highly doped source/drain extensions is confirmed by comparison of the results with those for a conventional single-materiel (SM) gate DM-JL-MOSFET, revealing a good improvement in sensitivity and making the proposed structure an attractive solution for use in DNA-based sensor applications.</style></abstract><issue><style face="normal" font="default" size="100%"> Issue 4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Kadri, A</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Menacer, Farid</style></author><author><style face="normal" font="default" size="100%">Zohir Dibi</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Performance analysis of a new graphene based-phototransistor for ultra-sensitive infrared sensing applications, ISSN 0030-4026</style></title><secondary-title><style face="normal" font="default" size="100%">Optik</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2018</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/abs/pii/S0030402618313494</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">176</style></volume><pages><style face="normal" font="default" size="100%">24-31</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	In this paper, a new Graphene nanoribbon (&lt;em&gt;GNR&lt;/em&gt;) based&amp;nbsp;&lt;em&gt;Ge&lt;/em&gt;-phototransistor is proposed and investigated numerically by self-consistently solving the Schrödinger equation and&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/poisson-equation&quot; title=&quot;Learn more about Poisson Equation from ScienceDirect's AI-generated Topic Pages&quot;&gt;Poisson equation&lt;/a&gt;&amp;nbsp;using&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/nonequilibrium&quot; title=&quot;Learn more about Nonequilibrium from ScienceDirect's AI-generated Topic Pages&quot;&gt;non-equilibrium&lt;/a&gt;&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/greens-function&quot; title=&quot;Learn more about Greens Function from ScienceDirect's AI-generated Topic Pages&quot;&gt;Green's function&lt;/a&gt;&amp;nbsp;(&lt;em&gt;NEGF&lt;/em&gt;) formalism. An overall performance metrics comparison between both the conventional&amp;nbsp;&lt;em&gt;Si&lt;/em&gt;-based&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/phototransistor&quot; title=&quot;Learn more about Phototransistor from ScienceDirect's AI-generated Topic Pages&quot;&gt;phototransistor&lt;/a&gt;&amp;nbsp;and the proposed design is performed. It is found that the proposed&amp;nbsp;&lt;em&gt;GNR Ge&lt;/em&gt;-phototransistor provides better electrical and optical performances compared to the conventional counterpart. Moreover, using&amp;nbsp;&lt;em&gt;GNR&lt;/em&gt;&amp;nbsp;material as a channel can improve the device performance not only enables a high&amp;nbsp;&lt;em&gt;I&lt;sub&gt;on&lt;/sub&gt;/I&lt;sub&gt;off&lt;/sub&gt;&lt;/em&gt;&amp;nbsp;ratio, but also allows achieving a superior sensitivity for ultra-low&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/optical-power&quot; title=&quot;Learn more about Optical Power from ScienceDirect's AI-generated Topic Pages&quot;&gt;optical powers&lt;/a&gt;. It is also revealed that the&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/responsivity&quot; title=&quot;Learn more about Responsivity from ScienceDirect's AI-generated Topic Pages&quot;&gt;responsivity&lt;/a&gt;&amp;nbsp;of the investigated design can be increased by reducing the&amp;nbsp;&lt;em&gt;GNR&lt;/em&gt;&amp;nbsp;channel length. This underlines the outstanding capability of the proposed design for bridging the gap between modern&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/nanoelectronics&quot; title=&quot;Learn more about Nanoelectronics from ScienceDirect's AI-generated Topic Pages&quot;&gt;nanoelectronic&lt;/a&gt;&amp;nbsp;and&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/nanophotonics&quot; title=&quot;Learn more about Nanophotonics from ScienceDirect's AI-generated Topic Pages&quot;&gt;nanophotonic&lt;/a&gt;&amp;nbsp;technologies. In addition, the proposed&amp;nbsp;&lt;em&gt;GNR&lt;/em&gt;-based&amp;nbsp;&lt;em&gt;Ge&lt;/em&gt;-phototransistor can achieve an acceptable detectivity for very weak optical power intensities, in the order of some&amp;nbsp;&lt;em&gt;Femto-Watts&lt;/em&gt;, which leads to reduce the total&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/electric-power-utilization&quot; title=&quot;Learn more about Electric Power Utilization from ScienceDirect's AI-generated Topic Pages&quot;&gt;power consumption&lt;/a&gt;&amp;nbsp;associated with&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/optical-link&quot; title=&quot;Learn more about Optical Link from ScienceDirect's AI-generated Topic Pages&quot;&gt;optical links&lt;/a&gt;. Therefore, the proposed&amp;nbsp;&lt;em&gt;GNR&lt;/em&gt;&amp;nbsp;phototransistor pinpoints a new path toward achieving an ultrasensitive photoreceiver with&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/low-power-consumption&quot; title=&quot;Learn more about Low Power Consumption from ScienceDirect's AI-generated Topic Pages&quot;&gt;low power consumption&lt;/a&gt;, which makes it potential alternative for chip-level Infrared communication and nano-optoelectronic applications.

	n this paper, we propose a new method for Bulk waves detection of an acoustic microwave signal during the propagation of acoustic microwaves in a piezoelectric substrate (Lithium Niobate LiNbO&lt;sub&gt;3&lt;/sub&gt;). We have used the classification by probabilistic neural network (PNN) as a means of numerical analysis in which we classify all the values of the real part and the imaginary part of the coefficient attenuation with the acoustic velocity in order to build a model from which we note the Bulk waves easily. These singularities inform us of presence of Bulk waves in piezoelectric materials.
&lt;/p&gt;

&lt;p style=&quot;text-align: justify;&quot;&gt;
	By which we obtain accurate values for each of the coefficient attenuation and acoustic velocity for Bulk waves. This study will be very interesting in modeling and realization of acoustic microwaves devices (ultrasound) based on the propagation of acoustic microwaves.

The transmittance spectra recorded for all films exhibit maxima exceeding 90%. The band gap energy of the films with wurtzite structure increases from 3.22 up to 3.60 eV by incorporating Mg into ZnO. However, when the atomic ratio of Mg exceeded 0.4, a second crystalline phase (assigned to cubic MgO) became discernable in XRD patterns, a compressive strain was observed in the wurtzite lattice, and crystallite sizes decreased significantly. In accordance with these observations, finer grains with a pronounced columnar growth were observed in 3D AFM representations and the surface roughness decreases significantly. Finally, selective etching in water yields to porous films with a great surface-to-volume ratio, a lower refractive index and a better light transmission. These porous films with tunable band gap seem to be excellent candidates to various interesting applications.</style></abstract><issue><style face="normal" font="default" size="100%">N°1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bendjerad, Adel</style></author><author><style face="normal" font="default" size="100%">Benhaya, Abdelhamid</style></author><author><style face="normal" font="default" size="100%">Boukhtache Sebti</style></author><author><style face="normal" font="default" size="100%">Zergoug, M</style></author><author><style face="normal" font="default" size="100%">Benyahia, Kaddour</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Modeling of magnetic properties (Cr/NiO/Ni) based multi-layers deposited by magnetron sputtering using Preisach model, ISSN 2495-3911</style></title><secondary-title><style face="normal" font="default" size="100%">Materials and Devices</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://hal.archives-ouvertes.fr/hal-01598150/document</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">2</style></volume><pages><style face="normal" font="default" size="100%">0310</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	: In the present work, thin films of Cr/NiO/Ni are deposited on glass substrates using RF magnetron sputtering technique. The uniformity and homogeneity of the prepared films were controlled by varying the power of the source, the targetsubstrate distance and the pressure of the plasma gas which is argon. In order to test the Preisach Model, we carried out measurements according to two directions: parallel and perpendicular to the substrate plane using a Vibrating Sample Magnetometer at room temperature. Good agreement has been obtained by comparing the experimental hysteresis loops to the ones determined using Preisach model. We conclude that this model is powerful in predicting the magnetic properties of multilayer systems.

	In the last few years, an accelerated trend toward the miniaturization of nanoscale circuits has been recorded. In fact, this has been reflected by numerous enhancements at different levels of multi‐gate structures such as the channel body or the gate material. Our aim in this work is to investigate the reliability performance of junctionless DG MOSFET including graded channel aspect. The behavior of the considered device is analyzed numerically using ATLAS‐2D simulator, where degradation phenomena are accounted for in the model. The variation of some analog/RF criteria namely the transconductance and cut‐off frequency are established in terms of the channel length and traps density. The obtained responses indicate the superior immunity of the graded channel device against traps‐induced degradation in comparison to the conventional structure. Thus, this work can offer more insights regarding the benefit of adopting the channel doping engineering for future nanoscale electronic applications.

	In this paper, a new particle swarm optimization‐based approach is proposed for the geometrical optimization of the nanowires solar cells to achieve improved optical performance. The proposed hybrid approach combines the 3‐D numerical analysis using accurate solutions of Maxwell's equations and metaheuristic investigation to boost the solar cell total absorbance efficiency. Our purpose resides on modulating the electric field and increasing the light trapping capability by optimizing the radial solar cell geometrical parameters. Moreover, a comprehensive study of vertical core‐shell nanowire arrays optical parameters such as the integral absorption, reflection, and total absorbance efficiency is carried out, in order to reveal the optimized radial solar cells optical performance for low‐cost photovoltaic applications. We find that the proposed hybrid approach plays a crucial role in improving the nanowires solar cells optical performance, where the optimized design exhibits superior total absorbance efficiency and lower total reflection in comparison with those provided by the conventional planar design.

	Bilayer of nickel and nickel oxide were deposited on glass substrates using RF&amp;nbsp;magnetron sputtering&amp;nbsp;technique. The&amp;nbsp;magnetic properties&amp;nbsp;of the prepared thin films were carried out at room temperature in both parallel and perpendicular&amp;nbsp;magnetic field&amp;nbsp;to the sample. The Preisach model was applied to provide a&amp;nbsp;mathematical model&amp;nbsp;of the magnetic&amp;nbsp;hysteresis&amp;nbsp;loop in the case of parallel geometry, along the easy axis of the bi-layer NiO / Ni. Good agreement was obtained between the theoretical and experimental results.

The overall solar cell optical performance comparison between the conventional design and a proposed design including three different intermediate metallic layers (&lt;em&gt;Au&lt;/em&gt;, &lt;em&gt;Ag&lt;/em&gt; and &lt;em&gt;Ti&lt;/em&gt;&lt;span&gt;) is carried out numerically using accurate solutions of Maxwell’s equations. It is found that the proposed design with intermediate metallic sub-layers’ engineering provides superior integral absorption in comparison to that offered by the conventional structure. Therefore, the introduced intermediate metallic layers play a &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/paramount-role&quot; title=&quot;Learn more about Paramount Role from ScienceDirect's AI-generated Topic Pages&quot;&gt;paramount role&lt;/a&gt; in increasing the light absorbance and modulate the electric field in the intrinsic region, where more light can be absorbed again by &lt;/span&gt;&lt;em&gt;a-Si&lt;/em&gt;&lt;span&gt; in the &lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/near-infrared&quot; title=&quot;Learn more about near Infrared from ScienceDirect's AI-generated Topic Pages&quot;&gt;near infrared&lt;/a&gt;&lt;span&gt; and &lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/infrared-region&quot; title=&quot;Learn more about Infrared Region from ScienceDirect's AI-generated Topic Pages&quot;&gt;infrared-regions&lt;/a&gt; using titanium as intermediate metallic layers. Furthermore, a hybrid computation based on combined numerical- metaheuristic modeling approach is proposed to boost the solar cell performance by optimizing the intermediate metallic layers. The obtained results indicate the advantage of the proposed design methodology in improving the amorphous solar cell performances.&lt;/span&gt;&lt;/span&gt;

				Recently, the Junctionless Double Gate MOSFET with source/drain extensions has proved competitive performance measures due to the reduction of the series resistance between the metal contacts and source/drain regions. However, the precise modeling of different response functions is still an important issue especially at nanoscale level because of the inclusion of complex phenomena such as quantum transport mechanisms and hot carrier degradation effect. In this perspective, our aim in the presented work is to investigate the efficiency of a novel approach based on Kriging metamodeling and multi-objective particle swarm optimization for the exploitation of the considered device in terms of some analog/RF performances. Data generated by ATLAS-2D simulator, are used to establish Kriging metamodels for the Gain and Transconductance Generation Factor. It is highlighted that the obtained models can be used accurately in a multi-objective context to offer several Pareto optimal configurations. As a result, a wide range of biasing configurations is available to the designer depending on imposed constraints.

Our purpose resides on reducing the refracting light and achieving an effective absorption in the Ag metallic sub-layers. New numerical model based on accurate solutions of Maxwell’s equations is developed in order to elucidate the impact of the metallic sub-layers on the UV-PD optical performance. An overall analysis regarding the optical parameters such as the integral absorption and the total reflection is conducted. It is found that the metallic sub-layers have profound implications on modulating the electric field in the structure and facilitating photon forward scattering in the ZnO sub-layers which led to better optical behavior. Moreover, Particle Swarm Optimization (PSO) approach is proposed as a metaheuristic technique to reach effectiveness absorption through carefully adjusting the Ag and ZnO sub-layers thickness. It is confirmed that the optimized design can provide superior optical performance as compared to the conventional counterpart, where the optimized multilayer design exhibits an enhancement of 60% in the integral absorption over ZnO-based PD. The obtained results make the proposed multilayer design efficient for providing high performance PDs for communication applications.</style></abstract><issue><style face="normal" font="default" size="100%"> Issue 7</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Hichem Ferhati</style></author><author><style face="normal" font="default" size="100%">Fouzi Douak</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Role of non-uniform channel doping in improving the nanoscale JL DG MOSFET reliability against the self-heating effects</style></title><secondary-title><style face="normal" font="default" size="100%">Superlattices and Microstructures</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/abs/pii/S074960361731008X</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Volume 109</style></volume><pages><style face="normal" font="default" size="100%">pp 869-879</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;span&gt;&lt;span&gt;In this paper, a new hybrid approach by combining numerical investigation and Support Vector Machines (SVMs) classifier is proposed to study the &lt;a href=&quot;https://www.sciencedirect.com/topics/materials-science/thermoelectrics&quot; title=&quot;Learn more about Thermoelectrics from ScienceDirect's AI-generated Topic Pages&quot;&gt;thermoelectric&lt;/a&gt; performance of &lt;/span&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/nanoscale&quot; title=&quot;Learn more about Nanoscale from ScienceDirect's AI-generated Topic Pages&quot;&gt;nanoscale&lt;/a&gt; Double Gate Junctionless &lt;/span&gt;&lt;span&gt;DG JL &lt;em&gt;&lt;a href=&quot;https://www.sciencedirect.com/topics/physics-and-astronomy/field-effect-transistors&quot; title=&quot;Learn more about Field Effect Transistors from ScienceDirect's AI-generated Topic Pages&quot;&gt;MOSFET&lt;/a&gt;&lt;/em&gt;&lt;/span&gt;.

	In this paper, an electromagnetic approach based on cavity model in conjunction with electromagnetic knowledge was developed. The cavity model combined with London’s equations and the Gorter-Casimir two-fluid model has been improved to investigate the resonant characteristics of high Tc superconducting circular microstrip patch in the case where the patch is printed on uniaxially anisotropic substrate materials.&amp;nbsp; Merits of our extended model include low computational cost and mathematical simplify. The numerical simulation of this modeling shows excellent agreement with experimental results available in the literature. Finally, numerical results for the dielectric anisotropic substrates effects on the operating frequencies for the case of superconducting circular patch are also presented.

	In this paper, the effects of both anisotropies in the substrate and superstrate loading on the resonant frequency and bandwidth of high-T&lt;em&gt;c&lt;/em&gt; superconducting circular microstrip patch in a substrate-superstrate configuration are investigated. A rigorous analysis is performed using a dyadic Galerkin's method in the vector Hankel transform domain. Galerkin's procedure is employed in the spectral domain where the TM and TE modes of the cylindrical cavity with magnetic side walls are used in the expansion of the disk current. The effect of the superconductivity of the patch is taken into account using the concept of the complex resistive boundary condition. London's equations and the two-fluid model of Gorter and Casimir are used in the calculation of the complex surface impedance of the superconducting circular disc. The accuracy of the analysis is tested by comparing the computed results with previously published data for several anisotropic substrate-superstrate materials. Good agreement is found among all sets of results. The numerical results obtained show that important errors can be made in the computation of the resonant frequencies and bandwidths of the superconducting resonators when substrate dielectric anisotropy, and/or superstrate anisotropy are ignored. Other theoretical results obtained show that the superconducting circular microstrip patch on anisotropic substrate-superstrate with properly selected permittivity values along the optical and the non-optical axes combined with optimally chosen structural parameters is more advantageous than the one on isotropic substrate-superstrate by exhibiting wider bandwidth characteristic.

Galerkin’s technique is used in the resolution of the integral equation of the electric field. The TM set of modes issued, from the magnetic wall cavity model, are used to expand the unknown currents on the circular patch. The radiation patterns are expressed regarding the transforms of the currents. The convergence of the method is proven by calculating the resonant frequencies, half-power bandwidths, and quality factors for several configurations. The computed results are found to be in excellent agreement with those observed in the literature. The numerical results obtained show that the bandwidth increases with the increase in the thickness of the suspended or composite substrates, especially for low permittivity of the second layer. Also, it is demonstrated that the resonant frequencies of the circular microstrip patch on suspended and composite substrates can be adjusted to obtain the maximum operating frequency of the antenna. Finally, the effect of the presence of the second layer under the circular patch on the radiation patterns is also investigated.</style></abstract><issue><style face="normal" font="default" size="100%">N° 3</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Barkat, Lamia</style></author><author><style face="normal" font="default" size="100%">Bedra, Sami</style></author><author><style face="normal" font="default" size="100%">Fortaki , Tarek</style></author><author><style face="normal" font="default" size="100%">Bedra , Randa</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Neurospectral computation for the resonant characteristics of microstrip patch antenna printed on uniaxially anisotropic substrates</style></title><secondary-title><style face="normal" font="default" size="100%">International Journal of Microwave and Wireless Technologies</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2017</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.cambridge.org/core/journals/international-journal-of-microwave-and-wireless-technologies/article/neurospectral-computation-for-the-resonant-characteristics-of-microstrip-patch-antenna-printed-on-uniaxially-anisotropic-substrates/859FA2B6042DA2</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">9</style></volume><pages><style face="normal" font="default" size="100%">613-620</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;div class=&quot;row&quot;&gt;

					Modeling and design of rectangular microstrip patch printed on isotropic or anisotropic substrate are accomplished in this paper. The use of spectral domain method in conjunction with artificial neural networks (ANNs) to compute the resonant characteristics of rectangular microstrip patch printed on isotropic or anisotropic substrates. The moment method implemented in the spectral domain offers good accurateness, but its computational cost is high owing to the evaluation of the slowly decaying integrals and the iterative nature of the solution process. The paper introduces the electromagnetic knowledge combined with ANN in the analysis of rectangular microstrip antenna on uniaxially anisotropic substrate to reduce the complexity of the spectral domain method and to minimize the CPU time necessary to obtain the numerical results. The numerical comparison between neurospectral and conventional moment methods shows significant improvements in time convergence and computational cost. Hence, the use of neurospectral approach presented here as a promising fast technique in the design of microstrip antennas.

	In this paper, a new particle swarm optimization‐based approach is proposed for the geometrical optimization of the nanowires solar cells to achieve improved optical performance. The proposed hybrid approach combines the 3‐D numerical analysis using accurate solutions of Maxwell's equations and metaheuristic investigation to boost the solar cell total absorbance efficiency. Our purpose resides on modulating the electric field and increasing the light trapping capability by optimizing the radial solar cell geometrical parameters. Moreover, a comprehensive study of vertical core‐shell nanowire arrays optical parameters such as the integral absorption, reflection, and total absorbance efficiency is carried out, in order to reveal the optimized radial solar cells optical performance for low‐cost photovoltaic applications. We find that the proposed hybrid approach plays a crucial role in improving the nanowires solar cells optical performance, where the optimized design exhibits superior total absorbance efficiency and lower total reflection in comparison with those provided by the conventional planar design. The obtained results make the proposed global optimization approach valuable for providing high‐efficiency nanowires solar cells.

Measurements show that the sensor achieves a comparatively high maximum measured efficiency of 41% for a power level of -10 dBm. The sensor has a simple structure, it is compact sized, light weight, and presents a high RF-to-DC conversion efficiency for low-RF-power levels which can be used to charge different low-DC-power devices.</style></abstract><issue><style face="normal" font="default" size="100%"> Issue 4</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>5</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bentercia, Toufik</style></author><author><style face="normal" font="default" size="100%">Fayçal Djeffal</style></author><author><style face="normal" font="default" size="100%">Elasaad Chebaki</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Multi-objective Design of Nanoscale Double Gate MOSFET Devices Using Surrogate Modeling and Global Optimization</style></title><secondary-title><style face="normal" font="default" size="100%">Intelligent Nanomaterials, II, Second Edition</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/308994823_Multi-objective_Design_of_Nanoscale_Double_Gate_MOSFET_Devices_Using_Surrogate_Modeling_and_Global_Optimization</style></url></web-urls></urls><publisher><style face="normal" font="default" size="100%">Willey</style></publisher><pages><style face="normal" font="default" size="100%">395-427</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	In recent years, the design and fabrication ofmulti-gate Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) have attracted more efforts due to their high appropriateness for advanced integration circuits' applications. In fact, the boost of MOSFET structures is a battle against parasitic phenomena appearing at the nanoscale level. Short channel and quantum confinement effects are among the critical drawbacks that need to be remedied carefully. On the other hand, the hot carrier degradation effect is mainly a reliability concern affecting the device per- formance after long duration of work. In response to the high computational costs related to the development of physi- cal based models for Double Gate (DG) MOSFETs including all these effects, more flexible alternatives have been proposed for the prediction of device performances. Our aim in this chapter is to investigate the efficiency of a new proposed frame- work, built upon Kriging metamodeling and Non-dominated Sorting Genetic Algorithm version II (NSGA II), for the optimal design in terms of OFF-current, threshold voltage and swing factor. The input variables of interest are limited to the geometrical parameters namely the channel length and thickness. Data generated according to computer experiments, based on ATLAS 2-D simulator, are used to identify and adjust Kriging surrogate models. It is emphasized that the obtained models can be used accurately in a multi-objective context to offer several Pareto optimal configurations. Therefore, a wide range of selection possibilities is avail- able to the designer depending on situations under consideration.

	Dans ce travail, nous proposons une nouvelle méthode pour la détection des micro-ondes acoustiques de volume dans un substrat piézoélectrique (Niobate de Lithium LiNbO3). Nous avons utilisé la classification par réseaux probabilistes de neurones comme un moyen d'analyse numérique afin de classer toutes les valeurs de la partie réelle et la partie imaginaire du coefficient d'atténuation pour les différentes vitesses acoustiques en construisant ainsi un modèle de détection efficace des ondes de volume. Cette étude sera très intéressante dans la modélisation et la réalisation des dispositifs micro-ondes acoustiques tels que les dispositifs à ultrasons basé sur la propagation des micro-ondes acoustiques de volume. En plus, nous pouvons appliquer cette technique sur n’importe qu’elle structure piézoélectrique possédant la même classe cristallographique, il suffit juste de changer les paramètres caractéristiques du matériau considéré.

	Iron thin films were deposited on glass substrates using RF magnetron sputtering and their optimal deposition conditions were determined. The structure properties were analyzed using x-ray diffraction (XRD) and their magnetic hysteresis loops were obtained by Vibrating Sample Magnetometer (VSM) at room temperature. In this situation, the magnetic field is either parallel or perpendicular to the substrate plane. The main contribution of this work is to characterize the thin layers and present a mathematical model that can get best fit of the characteristics B(H). By using Preisach model, good agreement was obtained between theoretical and experimental results in both cases.

	Silicon oxide (SiO&lt;sub&gt;2&lt;/sub&gt;) is a good dielectric material in metal-oxide-semiconductor (MOS) structures. The improved SiO&lt;sub&gt;2&lt;/sub&gt;&amp;nbsp;quality requires adequate study of doping diffusion in this structure to maintain the absence of the different impurities in the interface Poylsilicon/SiO&lt;sub&gt;2&lt;/sub&gt;. For this we studied a theoretical model of boron diffusion before and after thermal annealing in a highly-doped polysilicon films. The model takes into account the distribution of vacancy mechanism by associating parameters and effects related to high concentrations. Based on the literature the model is solved using the engineering software tool MATLAB, following a well-defined algorithm.

	The use of uniformly doped channel, source and drain regions presents the well-known problem of the high series resistance associated to the extensions, which degrades the electrical performance of the nanoscale multi-gate junctionless MOSFETs. Therefore, new designs and accurate investigation of nanoscale double gate junctionless (DGJ) MOSFET including the defects at the interface Si/SiO2 are required for the comprehension of the fundamentals of such device behavior against the ageing phenomenon. Based on 2D numerical investigation of a nanoscale DGJ MOSFET, in the present work a numerical study for I-V and small signal characteristics, by including both the highly doped extension regions and the interfacial defects, is presented. The investigated design, which is a technologically feasible technique by introducing only one ion implantation step, provides a good solution to improve the device immunity against the interfacial defects under critical conditions, where the channel length is taken equals to 10 nm. In this context, I-V, analog and linearity characteristics are investigated by an appropriate 2-D numerical modeling, where the obtained results are compared with those of the conventional DGJ MOSFETs.

	In this work, sol—gel dip-coating technique was used to elaborate ZnO pure and ZnO/Al films. The impact of Al-doped concentration on the structural, optical, surface morphological and electrical properties of the elaborated samples was investigated. It was found that better electrical and optical performances have been obtained for an Al concentration equal to 5%, where the ZnO thin films exhibit a resistivity value equal to 1.64104 Ω&lt;img align=&quot;absmiddle&quot; alt=&quot;centerdot&quot; src=&quot;https://ej.iop.org/icons/Entities/centerdot.gif&quot;&gt;cm. Moreover, highest transparency has been recorded for the same Al concentration value.

The analyzed microrobot is associated by a spherical head and hybrid tail. The principle of modeling is based on solving of the coupled elastic/fluidic problems between the hybrid tail’s deflections and the running environment. In spite of the resulting nonlinear model can be exploited to enhance both the sailing ability and also can be controlled in viscous environment using nonlinear control investigations. The applications of the micro-robot have required the precision of control for targeting the running area in terms of response time and tracking error. Due to these limitations, the Flatness-ANFIS based control is used to ensure a good control behavior in hazardous environment. Our control investigation is coupled the differential flatness and adaptive neuro-fuzzy inference techniques, in which the flatness is used to planning the optimal trajectory and eliminate the nonlinearity effects of the resulting model. In other hand, the neuro-fuzzy inference technique is used to build the law of control technique and minimize the dynamic error of tracking trajectory. In particular, we deduct from a non linear model to an optimal model of the design parameter’s using Multi-Objective genetic algorithms (MOGAs). In addition, Computational fluid dynamics modeling of the microrobot is also carried out to study the produced thrust and velocity of the microrobot displacement taking into account the fluid parameters. Our analytical results have been validated by the recorded good agreement between the numerical and analytical results.</style></abstract><issue><style face="normal" font="default" size="100%"> N°1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">R amdane Mahamdi</style></author><author><style face="normal" font="default" size="100%">Gouder, Soraya</style></author><author><style face="normal" font="default" size="100%">Stephanie Escoubas</style></author><author><style face="normal" font="default" size="100%">Luc Favre</style></author><author><style face="normal" font="default" size="100%">Mansour Aouassa</style></author><author><style face="normal" font="default" size="100%">Aantoine Ronda</style></author><author><style face="normal" font="default" size="100%">Isabelle Berezier</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Ge on porous silicon/Si substrate analyzed by Raman spectroscopy and atomic force microscopy</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of A dvanced Research in Physics</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://stoner.phys.uaic.ro/jarp/index.php?journal=jarp&amp;page=article&amp;op=view&amp;path%5B%5D=92&amp;path%5B%5D=93</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">6</style></volume><pages><style face="normal" font="default" size="100%">021609</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this study, single crystal Ge layers have been deposited by molecular beam epitaxy on PSi substrate, with different thicknesses (40 nm and 80 nm) at the growth temperature of 400Â°C.

	Multi-Gate Junctionless MOSFETs are promising devices to overcome the undesired short channel effects for low cost nanoelectronic applications. However, the high series resistance associated to the source and drain extensions can arise as a serious problem when dealing with uniformly doped channel, which leads to the degradation of the device performance. Therefore, in order to obtain a global view of Double-Gate Junctionless (DGJ) MOSFET performance under critical conditions, new designs and models of nanoscale DGJ MOSFET including analog performance are important for the comprehension of the fundamentals of such device characteristics. In the present paper, a numerical investigation for the drain current and small signal characteristics is conducted for the DGJ MOSFET by including highly doped extension regions. The proposed approach, which is from a practical viewpoint a feasible technique by introducing only one ion implantation step, provides a good solution to improve the drain current, small signal parameters, analog/RF behavior and linearity of DGJ MOSFET for high performance analog applications. In this context, &lt;em&gt;I&lt;/em&gt;–&lt;em&gt;V&lt;/em&gt; and analog characteristics of the proposed design are investigated by 2-D numerical modeling and compared with conventional DGJ MOSFET characteristics.

Moreover, using an analytical investigation, an overall performance comparison of the proposed dual texturized gate (DTG) OC-FET device and conventional OC-FETs has been studied in order to confirm the enhanced optical and electrical performance of the proposed design in terms of increased photoresponsivity (R), optical gain (Formula presented.) ratio, drain current driving capability (Formula presented.) and high signal to noise ratio. Simulations show very good agreement between the results of the developed analytical models and those of TCAD software for wide range of design parameters. The developed analytical models are used to formulate the objective functions to optimize the device performance using a multi-objective genetic algorithm (MOGA). The proposed MOGA-based approach is used to search the optimal design parameters, for which the electrical and optical device performance is maximized.

In this context, the proposed phototransistor owing to the high responsivity requires less optical power from the light emitter to achieve an acceptable signal-to-noise ratio compared to the phototransistor with conventional design.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ferhati Hichem</style></author><author><style face="normal" font="default" size="100%">Djeffal Fayçal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">New high performance ultraviolet (MSM) TiO2/Glass photodetector based on diffraction grating for optoelectronic applications, ISSN 0030-4026</style></title><secondary-title><style face="normal" font="default" size="100%">Optik</style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.sciencedirect.com/science/article/abs/pii/S0030402616304879</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">Volume 127</style></volume><pages><style face="normal" font="default" size="100%">pp 7202-7209</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this paper, a new TiO&lt;sub&gt;2&lt;/sub&gt;-based &lt;em&gt;UV&lt;/em&gt; photodetector including back triangular texturization morphology has been investigated numerically using accurate solutions of Maxwell’s equations. A quantitative study of the device optical parameters like responsivity, sensitivity, detectivity, derived current capability and signal to noise ratio have been carried out in order to review the device overall optical performance for &lt;em&gt;UV&lt;/em&gt; optical communication applications. Based on the obtained results, we have found that the device performance figures-of-merit (&lt;em&gt;FoMs&lt;/em&gt;) governing the optical behavior is strongly improved as compared to its conventional planar counterpart, where the proposed design offers superior photocurrent, higher responsivity and sensitivity in comparison with those provided by the planar structure. These results led us to suggest the optimization of the proposed morphology using genetic algorithm (&lt;em&gt;GA&lt;/em&gt;), in order to improve the electric field confinement and UV-light trapping in TiO&lt;sub&gt;2&lt;/sub&gt; absorber layer, where excellent ability has been recorded in enhancing the device absorbance. In this context, photodetector with optimized triangular texturization exhibits a 432% improvement, in term of responsivity, over planar structures and 120% improvement over the textured device without optimization. Thus, these encouraging results make the proposed device an extremely efficient candidate for high performance optoelectronic applications.</style></abstract><issue><style face="normal" font="default" size="100%">Issue 18</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Ferhati Hichem</style></author><author><style face="normal" font="default" size="100%">Djeffal Fayçal</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Role of Optimized Grooves Surface-Textured Front Glass in Improving TiO2 Thin Film UV Photodetector Performance, ISSN / e-ISSN 1530-437X / 1558-1748</style></title><secondary-title><style face="normal" font="default" size="100%"> IEEE Sensors Journal </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://ieeexplore.ieee.org/document/7480766</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%"> Volume 16 </style></volume><pages><style face="normal" font="default" size="100%"> pp 5618-5625</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this paper, the impact of the surface-textured front glass on the absorption of TiO &lt;sub&gt;2&lt;/sub&gt; /glass thin-film ultraviolet (UV) photodetector is investigated, in order to achieve the dual role of increasing the scattering of UV-light as well as reducing the refracting UV-light in the glass. The efficient control of these phenomena may lead to more electric field confinement and UV-light trapping in TiO &lt;sub&gt;2&lt;/sub&gt; absorber layer. Moreover, semianalytical modeling combined with particle swarm optimization is carried out for studying and enhancing the metal-semiconductor-metal photodetector optical and electrical performances. The results obtained from our semianalytical investigation are validated by comparison with the experimental data. It is found that the absorbance increases significantly by about 51% in optimized design over the planar structure, which is expected to improve the photodetector figures of merit. In this context, photodetector with optimized grooves texturization exhibits a 341% improvement, in terms of responsivity, in comparison with the planar structure and 275% improvement with respect to the textured device without optimization.

The proposed neural network control (NNC) strategy is designed to produce regulated variable DC output voltage. The mathematical model of Cuk converter and artificial neural network algorithm is derived. Cuk converter has some advantages compared to other type of converters. However the nonlinearity characteristic of the Cuk converter due to the switching technique is difficult to be handled by conventional controller. To overcome this problem, a neural network controller with online learning back propagation algorithm is developed. The NNC designed tracked the converter voltage output and improve the dynamic performance regardless load disturbances and supply variations. The proposed controller effectiveness during dynamic transient response is then analyze and verified using MATLAB-Simulink.

Maximum power point tracking (MPPT) plays an important role in photovoltaic systems because it maximizes the power output from a PV solar system for all temperature and irradiation conditions, and therefore maximizes the power efficiency. Since the maximum power point (MPP) varies, based on the PV irradiation and temperature, appropriate algorithms must be utilized to track it in order maintain the optimal operation of the system. The software Matlab/Simulink is used to develop the model of PV solar system MPPT controller. The system simulation is elaborated by combining the models established of solar PV module and a DC/DC Boost converter. The system is studied using various irradiance shading conditions. Simulation results show that the photovoltaic simulation system tracks optimally the maximum power point even under severe disturbances conditions.</style></abstract><issue><style face="normal" font="default" size="100%">Issue 1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Zerdoumi,  Zohra</style></author><author><style face="normal" font="default" size="100%">Chikouche, Djamel</style></author><author><style face="normal" font="default" size="100%">Benatia, Djamel</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">An improved back propagation algorithm for training neural network-based equaliser for signal restoration in digital communication channels</style></title><secondary-title><style face="normal" font="default" size="100%">International Journal of Mobile Network Design and Innovation </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/312665945_An_improved_back_propagation_algorithm_for_training_neural_network-based_equaliser_for_signal_restoration_in_digital_communication_channels</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">6</style></volume><pages><style face="normal" font="default" size="100%">236 - 244</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p style=&quot;text-align: justify;&quot;&gt;
	The back propagation (BP) algorithm has been very successful in training multilayer perceptron-based equalisers; despite its success BP convergence is still too slow. Within this paper we present a new approach to enhance the training efficiency of the multilayer perceptron-based equaliser (MLPE). Our approach consists on modifying the conventional back propagation algorithm, through creating an adaptive nonlinearity in the activation function. Experiment results evaluates the performance of the MLPE trained using the conventional BP and the improved back propagation with adaptive gain (IBPAG). Due to the adaptability of the activation function gain the nonlinear capacity and flexibility of the MLP is enhanced significantly. Therefore, the convergence properties of the proposed algorithm are more improved compared to the BP. The proposed algorithm achieves the best performance in the entire simulation experiments.

	Impact of nonlinear piezoelectric constants on surface acoustic wave propagation on a piezoelectric substrate is investigated in this work. Propagation of acoustic wave propagation under uniform stress is analyzed; the wave equation is obtained by incorporating the applied uniform stress in the equation of motion and taking account of the set of linear and nonlinear piezoelectric constants. A new method of separation between the different modes of propagation is proposed regarding the attenuation coefficients and not to the displacement vectors. Detail calculations and simulations have made for Lithium Niobate (LiNbO3); transformations between modes of propagation, under uniform stress, have been found. These results leads to conclusion that nonlinear terms affect the acoustic wave propagation and also we can make controllable acoustic devices.

	&lt;span id=&quot;ctl00_cphFeatured_lblAbstract&quot;&gt;Neural network based equalizers can easily compensate channel impairments; such additive noise and inter symbol interference (ISI). The authors present a new approach to improve the training efficiency of the multilayer perceptron (MLP) based equalizer. Their improvement consists on modifying the back propagation (BP) algorithm, by adapting the activation function in addition to the other parameters of the MLP structure. The authors report on experiment results evaluating the performance of the proposed approach namely the back propagation with adaptive activation function (BPAAF) next to the BP algorithm. To further prove its effectiveness, the proposed approach is also compared beside a so known nonlinear equalizer explicitly the multilayer perceptron with decision feedback equalizer MLPDFE. The authors consider various performance measures specifically: signal resorted quality, lower steady state MSE reached and minimum bit error rate (BER) achieved, where nonlinear channel equalization problems are employed.&lt;/span&gt;

	This paper presents a simple approach for accurate determination of the resonant frequency of an elliptical microstrip patch printed on isotropic or anisotropic substrate materials. In this approach, some modifications are made to account for fringe fields, dispersion effects, and losses by calculating effective dimensions, effective permittivity of anisotropy in the layer, and effective loss tangent, respectively. The theoretical resonant frequency results are in very good agreement with the experimental results reported elsewhere. Numerical results show that the change in the resonant frequency of the antenna is due primarily to a small disturbance of the substrate's nature. Then the effect of the uniaxial anisotropic materials is a significant parameter and most essential on the microstrip antenna characterization.

Based on modified ground plane and loop feeding structure, the first design solution consist to propose a simple technique which not requires any discrete additional elements or circuits and does not affect the overall dimensions of the basic structure. This technique enhances the (-6 dB) bandwidth of the planar monopole antenna by approximately 50% compared to the basic structure while maintaining the same dimension (30 × 10 mm2). The optimized proposed antenna presents a large bandwidth, good radiation stability, total efficiency higher than 70% over the entire band and small size (30 × 10 mm2) which will enable to use it in different UWB applications. In the second step, two L slots are added in the printed circuit board of the proposed UWB antenna to reach a good stability of the radiation pattern on the overall desired band.</style></abstract><issue><style face="normal" font="default" size="100%">N°8</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bedra Sami</style></author><author><style face="normal" font="default" size="100%">Fortaki Tarek</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Resonant and Radiation Characteristics of Rectangular Microstrip Patch Antenna on Suspended-Composite Substrates, ISSN 1054-4887</style></title><secondary-title><style face="normal" font="default" size="100%">Applied Computational Electromagnetics Society Journal </style></secondary-title></titles><dates><year><style  face="normal" font="default" size="100%">2016</style></year></dates><urls><web-urls><url><style face="normal" font="default" size="100%">https://www.researchgate.net/publication/300335944_Resonant_and_Radiation_Characteristics_of_Rectangular_Microstrip_Patch_Antenna_on_Suspended-Composite_Substrates</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">volume 31</style></volume><pages><style face="normal" font="default" size="100%">pp 138-142</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In this paper, the resonance and radiation characteristics of rectangular microstrip patch printed on suspended and composite substrates are investigated theoretically.
