Abstract

A photodetector includes a first electrode; an interlayer disposed on the first electrode; a photoabsorbing layer disposed on the interlayer, the photoabsorbing layer having one or more charge transport materials, and a plurality of two-dimensional quantum dots (2D QDs) dispersed in the one or more charge transport material; and a second electrode disposed on the photoabsorbing layer. A heterostructure photodetector includes a first electrode; a first photoabsorbing layer disposed on the first electrode, the first photoabsorbing layer having a first photoabsorbing material; a second photoabsorbing layer disposed on the first photoabsorbing layer, the second photoabsorbing layer having a second photoabsorbing material; and a second electrode disposed on the second photoabsorbing layer.
