Progress in piezotronics and piezo-phototronics of quantum materials

Piezotronic and piezo-phototronic effects reveal promising applications in the third-generation semiconductors with non-centrosymmetric structures. With the size of piezoelectric materials reducing to nanoscale, quantum wave behavior and some interesting quantum effects will appear. This paper aims to offer a summary of the rapid advancements made in piezotronics and piezo-phototronics of quantum materials and present a perspective on their applications. Furthermore, several significant quantum phenomena manipulated by the piezotronic or piezo-phototronic effect are highlighted. The coupling between piezotronics/piezo-phototronics and quantum physics opens up a new avenue for next-generation high-integration, ultra-fast and hypersensitive electronic/optoelectronic systems.
