| 摘 要： | 报道了 MBE外延生长的 Gax In1 - x Asy Sb1 - y四元混晶的拉曼散射谱与远红外反射谱 ,并从拉曼散射谱中观察到了 Gax In1 - x Asy Sb1 - y四元混晶的晶格振动四模行为 ;从实验中还观察到低于 180 cm- 1的若干散射峰 ,提出它们可能是与次近邻原子间相互作用的晶格振动模式有关 ;从拉曼散射谱和红外反射谱中观察到了与 Gax In1 - xAsy Sb1 - y四元混晶多声子吸收过程的有关的现象

| Abstract: | The long wavelength optical phonons in Ga x In 1- x As y Sb 1- y MBE epitaxial layers were investigated by Raman scattering spectroscopies and FIR reflection spectra. The four mode behavior and modes below 180cm -1 related with the interaction between the third nearest atoms in Ga x In 1- x As y Sb 1- y quaternary mixed crystals were observed from the Raman data, and the related phenomenon possibly arising from the multi phonon absorption process was observed from the FIR and Raman data. |
