Abstract

This work demonstrates large-area ( 4cm 2 ) UV photodetector by heterogenous integration of graphene-ZnO nanowires (NWs) using a facile and cost-effective method. Owing to the low and wavelength-independent light absorption, it is difficult to obtain high-performance graphene-based photodetector (PD). The research presented here addresses this challenge by integrating light sensitive material (ZnO) on graphene. The huge sensitivity of ZnO NWs to UV light, combined with the high carrier mobility of graphene, enable the UV PD with a photoresponse up to 2100 A/W, and fast response times down to millisecond.
