摘　　要：报导了用红外椭圆偏振光谱测定的不同组分 GaxIn1－ xAsySb1－ y材料室温光学常数（ n和α） ,并且实验观察到明显的折射率增强效应 ,发现组分在 x=0.2～ 0.3之间折射率峰值随组分 x近似于线性变化。The optical constants of GaxIn1－ xAsySb1－ y MBE epitaxy layers with different compositions were studied by infrared ellipsometric spectroscopy at room temperature. The refraction indices enhancement were experimentally observed. The peak values of refractive indices change approximately as a linear function of composition between x=0.2～ 0.3.
