Silicon-Graphene Heterostructure: A Promising Platform for Near/Mid-IR Photodetection

The integration of silicon and graphene into a heterostructure presents a compelling alternative for photodetection in the near/mid-infrared (NIR/MIR) spectral region. This approach holds significant promise due to its inherent advantages, namely, straightforward fabrication procedures and a minimized dark current. The synergistic combination of silicon's well-established semiconductor properties and graphene's exceptional electrical conductivity and broad spectral response enables the development of high-performance NIR/MIR photodetectors. This research investigates the fundamental principles and potential applications of silicon-graphene heterostructures in the context of NIR/MIR photodetection, emphasizing the advantages associated with their fabrication and performance characteristics.
