摘要
本文首次在室温和0—2.5GPa静压范围内研究了Znse/Zn0.26Cd0.26Se应变超晶格的静压光致发光,观察到了室温条件下的超晶格阱层的重空穴激子跃迁随压力的亚线性变化的特性.经过计算机拟合实验数据得到了一阶和二阶压力系数.理论计算得到的一阶压力系数与实验得到的压力系数符合得较好。
A study of the photoluminescence of ZnSe/ZnCdSe strained superlattices under hydrostatic pressure at room temperature has been performed for the first time. The small sublinear dependence of PL energy with pressure for the heavy-hole exciton of the well layers was obtained. The linear pressure coefficient obtained by calculation is well agreement with the experimental data.The discussion about the phenomena under hydrostatic pressure was given.
