Abstract
We have studied the resonance of the first- and second-order Raman scattering by LO phonons in CdxHg1-xTe for x1 near the E0+0 gap. We show that the effect of alloying is a shift and a broadening of the resonances which can be compared with calculations of the compositional dependence of the gaps. The mechanisms contributing to one-LO-phonon and two-LO-phonon scattering are discussed and experimentally investigated. We give absolute values for the Raman efficiencies and compare them with theory.
