Abstract

Abstract Pyro-phototronic effect has attracted much attention in fabricating self-powered high-performance photodetectors because of the significant enhancement by modulating the separation, transportation, and extraction of photo-generated electron-hole pairs in optoelectronic processes. This review highlights the advances in fabricating pyro-phototronic effect enhanced photodetectors. The fundamental research on the enhanced mechanism is discussed. Various device structures and figure of merit are summarized to demonstrate the improvement of performance by pyro-phototronic effect. Synergetic effects dominated by pyro-phototronic effect are also discussed to show their great potential and the universality of applying pyro-phototronic effect in photodetection. Finally, an outlook is delivered, and future research directions and challenges are discussed.
