Abstract

Abstract: We exploit the broad-band transparency of graphene and the favorable energy band line-up of graphene with n -type InSe thin films to create graphene-InSe-graphene heterostructures with high photosensitivity at room temperature. We use a semiclassical model to describe the photoresponse and its dependence on the electron transit time through the InSe layer.
