Abstract
Devices fabricated by using the inner-crystal piezopotential as a “gate” voltage to tune/control the carrier generation, transport, and recombination processes at the vicinity of a p–n junction are named piezo-phototronics. The presence of piezoelectric charges at the interface/junction can significantly affect the charge carrier separation and transport. This chapter focuses on the basic theory for the piezo-phototronic effect on LED, photon detector, and solar cell. Both analytical equations and numerical simulations are given to present the basic physics for understanding the general phenomena.
