Raman scattering in mixed crystal semiconductors
"We have studied the effects of substitutional disorder on the inelastic light scattering by phonons in three semiconductor alloys; (GaSbh-x(Ge2)x, GaAsxSbl-x' and AlxGal-xAs. We measure the asymmetric broadening and shifting of the longitudinal optic (LO) phonon lines as a function of disorder and …
