Overview and research status of graphene photodetectors
Application prospects of graphene photodetectorsGraphene has characteristics such as ultra-high carrier mobility, wide spectral absorption, and extremely high thermal conductivity,These excellent properties lay the foundation for the preparation of photodetectors with high sensitivity and wide spectral response.However, due to the inherent zero bandgap energy band structure of graphene, its light absorption ability is weak, and there are also shortcomings such as small gain mechanism and fast carrier recombination rate, which limit the application of pure graphene in photodetectors...
