摘    要:通过对Zn xCd1 - xTe- ZnTe 多量子阱的光致发光研究,讨论了该材料的谱线增宽效应。指出材料阱层的组分涨落是激子谱线非均匀增宽的主要来源,而由流体力学性质决定的涨落,在组分张落中起着非常重要的作用。

关 键 词:多量子阱  激子  非均匀增宽  组分涨落

Abstract:Based on the study of Zn x Cd 1- x Te-ZnTe multiple quantum well,we have investigated the effects of its spectrum line broadening.It is demonstrated that the compositional fluctuation is the main cause of inhomogeneous broadening,whereas the fluid-dynamics-dependent fluctuation plays a very important role in the compositional one.
Keywords:multiple quantum well  exciton  inhomogeneous broadening  compositional fluctuation
