Graphene/PtSe<sub>2</sub>/Ultra-Thin SiO<sub>2</sub>/Si Broadband Photodetector with Large Responsivity and Fast Response Time

Graphene/PtSe<sub>2</sub>/Ultra-Thin SiO<sub>2</sub>/Si Broadband Photodetector with Large Responsivity and Fast Response Time

Burgeoning two-dimensional (2D) materials provide more opportunities to overcome the shortcomings of silicon-based photodetectors. However, the inevitable carrier loss in the 2D material/Si heterojunction has seriously hindered further improvement in responsivity and detection speed. Here, we propos...
