摘要
AlAs/InAs strained layer superlattices have been grown pseudomorphically on {100}, {311} and {211} GaAs substrates by atomic layer molecular beam epitaxy. Optical characterization has been performed by piezoreflectance and Raman spectroscopies. A two coupled modes linear chain model has been developed for {xi-11} (xi = 2, 3) superlattices phonon modes calculation taking into account the effect of strain. Phonon modes calculations for the {311} AlAs/InAs superlattice are in very good agreement with the experimental Raman results.
