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
The Raman scattering spectra and far infrared reflection spectra of the Gax In1 - x Asy Sb1 - y quaternary mixed crystals grown by MBE were reported. The Gax In1 - x Asy Sb1 - y quaternary mixed crystals were observed from Raman scattering spectra The experimental results also show that there are some scattering peaks below 180 cm-1, suggesting that they may be related to the lattice vibrational modes of the next-nearest-neighbor atomic interaction.
