Abstract

We report on manipulating the stimulated emission of monolayer molybdenum disulfide (MoS2) with the piezoelectric effect. The analysis is based on quantum mechanics. The stimulated emission of this two-dimensional material has been simulated to establish the relation between the total emission rate...
