High-Performance Self-Powered PbSe/Ag2Se Heterojunction Photodetector Enabled by Annealing-Induced in Situ Electrode Phase Conversion

Lead selenide (PbSe) thin films are attractive for room-temperature infrared photodetection, yet efficient self-powered operation relies on the construction of a high-quality heterojunction. Herein, an asymmetric Ag/PbSe/Ni electrode structure was fabricated and subsequently anne...
