Abstract
Experimental results obtained on CdS, ZnO, and CdSe are presented which show electron‐beam‐pumped laser emission resulting from the decay of free excitons to photons and longitudinal optical (LO) phonons. Calculations based on available absorption data for ZnO and CdS show that at 77°K the required exciton density for stimulated emission is about 1017 and 1018 cm−3, respectively.This publication has 10 references indexed in Scilit:
