| 摘 要： | 本文给出了ＣａＡｓ衬底上生长的ＺｎＳｅ－ＺｎＳ应变超晶格的室温Ｒａｍａｎ分析，观测了该超晶格中ＺｎＳｅ子层和ＺｎＳ子层的纵光学振动模（ＬＯ），首次发现在一些样品中ＺｎＳｅ子层的纵光学声子模ＬＯＺｎＳ出现红移，另一些样品中ＬＯＺｎＳｅ出现蓝移，而ＺｎＳ子层的ＬＯＺｎＳ总是向低波数方向移动，并利用限制效应和应变效应给出了解释。

| Abstract: | The room temperature Raman scattering study of ZnSe-ZnS superlattice grown on (100) is reported. The longitudinal optical modes (LO) of ZnSe-like and ZnS-like in ZnSeZnS superlattice have been observed. The Raman red shifts of ZnSe-like LO-phonon have been found for the first time in some samples, meanwhile the blue shifts of ZnSe LO-phonon have been found in other samples. However, for ZnS-like LO-phonon, the red shifts occur in all samples. This phenomena can be explained by strain and confinement effects. |
