本文在LMTO-ASA能带计算中,采用冻结声子模型,系统地研究了Ⅲ-V族化合物半导体的Λ轴光学声子形变势随k值的变化关系,提供了9种Ⅲ-V族化合物在Λ轴不同k值情况下的光学声子形变势d30(Λ), d10(Λ,val)和d10(Λ,con)的第一原理计算结果。The study of optical-phonon deformation potentials (ODP*s) versus wavevector on 1111A-axis in Brillioun zone for nine III-V compound semiconductors is carried out systematically, based on ab initio LMTO-ASA band calculation within the frozen-phonon approximation model. The ODP*s d30(∧),d10(∧,val) and d10(∧,con) obtained from the calculation are presented.
