Modulated spectroscopy of zincblende semiconductors. Calculation of piezomodulation parameters for indirect semiconductors

Abstract
Relative modulation parameters are calculated for the absorption coefficient in the indirect absorption edge region for periodically stressed zincblende‐type semiconductors. The calculations are made for [001] and [111] uniaxial and coplanar stresses, for all possible phonons, for all independent polarizations of light, and through all relevant intermediate states (Γ1c, Γ15c and X5v or L3v).
