Impurity induced Raman scattering spectra in zincblende-type crystals: application to mixed indium pnictides

Abstract
A theoretical study of impurity-induced first-order Raman scattering has been reported for zincblende-type crystals using Green function techniques. The perturbation model parameters obtained from the analysis of localised and gap modes have been incorporated to compute the Raman scattering structure for mixed indium pnictides in the low-impurity concentration limit. The calculated results correspond very well with the existing experimental data of Carles et al. (1978).
