Enhancing the Photoresponsivity and External Quantum Efficiency of ReSe₂ Photodetectors Through the Insertion of a Graphene Auxiliary Layer.

ABSTRACT: Two-dimensional (2D) materials demonstrate significant potential in photodetector technology. They offer high sensitivity, wide spectral range, flexibility and transparency, especially in infrared detection, promising advancements in wearable and flexible electronics. This study explores the application of 2D materials in high-performance photodetectors. Rhenium diselenide (ReSe₂) was used as the channel, and graphene (Gr) was inserted between ReSe₂ and SiO₂ as the gate electrode to enhance device performance. A ReSe₂/Gr heterostructure field-effect transistor (FET) was fabricated to investigate the role of Gr in improving the optoelectronic properties of ReSe₂ phototransistors. Specifically, the ReSe₂ FET without Gr auxilia
