| 摘 要： | 运用分子束外延（ＭＢＥ）技术成功地生长出Ｚｎ１－ｘＣｄｘＳｅ／ＺｎＳｅ超晶格，并对不同的样品进行了拉曼散射光谱的测试。获得了多达５级的ＺｎＳｅ的ＬＯ声子峰和ＺｎＳｅ的ＴＯ声子峰；同时还在频移为１４４ｃｍ－１、３７０ｃｍ－１处观测到了两个新声子峰，估计是来自于ＺｎＣｄＳｅ的声学模和光学模。

| Abstract: | We have successfully grown Zn1-xCdxSe/ZnSe superlattices by MBE, and measured the Raman scattering spectra of different samples. UP to five LO phonon peaks and one TO pnonon peak of ZnSe have been observed. Two new phonon peaks were obtained at frequency shift 144 cm-1 and 370 cm-1, which maybe resulted from the acoustic mode and optical mode of ZnCdSe. |
