摘要: 讨论了Hg1-xCdxTe外延薄膜的自由载流子吸收光谱，分析了外延层的纵向组分分布及Ｔｅ沉淀物对吸收曲线的影响．结果表明，由于外延薄膜存在着纵向组分的不均匀性，其吸收特性与体材料有区别；对某些透过率较低的样品，则应考虑Ｔｅ沉淀物对吸收的贡献

Abstract: The free carrier absorption spectra for Hg1-xCdxTe epilayers are derived by considering the composition-in-depth nonuniformity and Te precipitates in the epilayers. The results show that the absorption behaviour of epilayers exhibits many differences with that of the bulk materials. The Te precipitates may exist when the calculated transmission is much higher than the experimental data.
