Design and manipulation of heterojunction for graphene composite structure photoconductive photodetector

As a typical atomically thin two-dimensional (2D) crystal, graphene-based photodetector has attracted tremendous attention in recent years due to excellent photoelectric performance of graphene. However, due to the unstable chemical properties of graphene, the guidance is lacking in the design of composites with other materials. The stability and repeatability of the device are also restricted by the material properties. Here, we have...
