Abstract

Broadband photodetectors are becoming attractive in all weather and all time detection. However, silicon, germanium or compound semiconductors could not cover the visible and infrared wavebands which are commonly used in optoelectronic application. Here, we demonstrate a broadband photodetector based on graphene and silicon nanocrystals which are all CMOS-compatible. We achieved a photodetector which photoelectric response range covering visible and infrared (400-1600nm) and peak response up to 630mA/W. Furthermore, the photoelectric response time lower than 50μs.
