摘要
本文模拟计算了ＣｄＴｅ 中Ｔｅ 沉淀相对红外光的散射吸收作用及其对入射光能量和Ｔｅ沉淀相尺寸的依赖关系，根据光透射比分别处理了ＣｄＴｅ 的吸收和Ｔｅ 沉淀相的散射吸收消光作用．结合光致发光和电学特性的研究，讨论了Ｃｄ 气氛中的退火对ＣｄＴｅ 晶体的红外消光特性的影响．
The infrared extinction due to the scattering by Te precipitates is simulated, and the Cd\|annealing pressure dependence of the infrared extinction in CdTe is investigated with infrared transmittance, photoluminescence and Hall measurements.The results suggest that the IR extinction is dominated by the absorption at lower energy and by precipitates scattering at higher energy,respectively,and both could be improved by Cd\|annealing.
