	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.
