Abstract

Abstract Self‐powered photodetection is an effective way to resolve the issue of high dark current in infrared photodetectors under a bias voltage. To date, high‐performance infrared self‐powered photodetectors (ISPDs) are mostly based on heterostructures consisting of 2D and 3D materials, while those based on 2D/2D heterostructures are rare. This will hinder the development of infrared devices toward miniaturization and energy‐saving. By exploring some 2D/2D van der Waals (vdWs) heterostructures, constructed by typical 2D transition metal dichalcogenides (TMDs), it is found that the heterostructure PdSe 2 /MoTe 2 is a high‐performance ISPD. It exhibits a good capability of self‐powered broadband detection…
