Photoresponsive Devices: Ultrahigh Photoresponsive Device Based on ReS₂ /Graphene Heterostructure (Small 45/2018)

In article number 1802593, Changgu Lee and co-workers develop a photodetector based on a ReS2/graphene heterostructure, which exhibits outstanding photoresponsivity, detectivity, and ultrafast responsivity due to the excellent light absorption property of ReS2 and high carrier mobility of graphene. The interface between ReS2 and graphene facilitates a high photocurrent because of the photogating effect under the applied gate voltage.
