Abstract

Abstract : This study demonstrates significant improvements of ZnO nanowire lasers by the piezophototronic effect . The laser output power can be enhanced by a factor of 4.96, and the threshold voltage can be decreased from 48 to 20 V by applying pressure. The mechanism of the improved performance can be attributed to the enhanced carrier injection and recombination due to the piezophototronic effect.
