Abstract
The piezophototronic effect is the coupling of piezoelectricity, semiconductor behavior and photon excitation in wurtzite materials, which can enhance the performance of optoelectronic nano-devices by regulating a series of processes of carrier injection, transport, and recombination. In recent years, many research results have been reported on the improvement of nanophotoelectric nano-device efficiency by piezophototronic effect, such as photovoltaic devices, light-emitting devices, transistors, etc. Herein, the research results of piezophototronic effect in the field of nanosensors, including enhancing the performance of traditional nanosensors and new types of pressure/deformation/tactile sensors based on piezophototronic effect are comprehensively summarized. Finally, the future development of piezophototronic effect in the field of nanosensors is discussed.
