EXCITON DYNAMIC AND STIMULATED EMISSION IN ZnSe ZnS MQWs

本文讨论了在ＺｎＳｅ薄膜材料及ＺｎＳｅ－ＺｎＳ多量子阱中宽阱材料和窄阱材料的激子弛豫过程和在窄阱材料中激子受激发射

This paper discusses the relaxation processes of exciton in ZnSe thin film and mul tiple quantum wells (MQWs) and the stimulated emission of exciton in narrow well of MQWs. The nonradiative processes of exciton is the leading facter in the ZnSe thin film. The nonradiative relaxation processes were checked in MQWs. The check effectiveness increases with decreasing well width. The stimulated emission have been acquired easily in low dimension material.
