GaAs中碳受主局域振动模光吸收特性

Characteristics of Local Vibrational Mode Optical Absorption for Carbon Acceptor in GaAs

在 ＧａＡｓ中碳受主局域振动模光吸收主带的低能侧发现一个吸收边带．研究了该边 带的起因及其对主吸收带积分面积测定和主吸收带积分面积温度关系的影响．

A sideband absorption is observed on the low energy side of the main optical absorption band of the local vibrational mode for carbon acceptor in GaAs. The possible origin for the sideband is suggested, and the effects of this sideband on both the measurement of the integrated area of the main absorption band and the temperature dependence of the main band are also investigated.
