Abstract
In this article, we report that the photoconductive gain of the photodetector can be appreciably increased by forming a heterojunction between silicene and MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> . To the best of the authors' knowledge, it is for the first time that the silicene/MoS <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> heterojunction has been investigated as a high-performance device for photodetector applications. Density function theory is used to study the performance of the photodetector in terms of performance parameters like responsivity, detectivity, and optical gain. A comparison of the proposed photodetector with the state-of-the-art photodetectors available in the open literature reveals that the proposed photodetector offers improved performance over the reported photodetectors.
