Systematic theoretical studies of Raman spectra of \(\mathrm{GaAs}-\mathrm{Al}_{x} \mathrm{Ga}_{1-x} \mathrm{As}\) superlattices are presented. The electronic states are described by an envelope-function method and the phonon modes are described in a microscopic rigid-ion model. Both resonant and no
