摘要
利用远红外反射光谱和拉曼散射光谱法测量了 Ga As/ Sr Ti O3外延单晶薄膜样品 ,研究了这种新型异质结构的晶格振动光学特性 .实验结果表明 :在钙钛矿型结构的 Sr Ti O3衬底上外延生长的 Ga As薄膜具有单晶结构 ,有与 Ga
With the far IR spectroscopy and Raman scattering spectroscopy, the crystal lattice vibration and optical properties of the GaAs single crystal film on the perovskite oxide SrTiO 3 (001) substrate were studied. The result of the measurement shows that the GaAs film on SrTiO 3 (001) substrate by MBE is a single crystal film and the lattice vibration property of the GaAs single crystal film is similar to that of the GaAs bulk material.
