Paper Abstract

Blue-green and blue stimulated emission under photopumping in Zn0.8Cd0.2Se-ZnSe and ZnSe-ZnS multiple quantum wells (MQWs) on (100) GaAs substrate grown by atmospheric pressure metalorganic chemical vapor deposition (AP-MOCVD) have been investigated, respectively. For the Zn0.8Cd0.2Se-ZnSe MQWs, the stimulated emission of the sample with different cavity length is observed at 77K, two groups of stimulated emission lines observed are attributed to n equals 1 heavy- hole (hh) and light-hole (lh) exciton transition, respectively, and it is noticed that the sample with the shorter Fabry-Perot cavity length has the larger threshold excitation and more mode spacing. For the ZnSe-ZnS MQWs, the blue stimulated emission is observed and attributed to the exciton-exciton interactions.
