Detrapping of the carriers from shallow states in a highly responsive, fast, broadband (UV-vis-NIR), self-powered SnSe/Si photodetector with asymmetric metal electrodes

Abstract

Tin-selenide (SnSe), an eco-friendly and low-cost semiconductor material, has exhibited great potential to detect weak light signals and has wide applications in imaging and optical communication. Here, self-powered SnSe-based photodetectors...
