Raman scattering in two Ga0.47In0.53As/InP superlattices is reported. Scattering by folded longitudinal acoustic phonons has been observed and interpreted using the elastic continuum theory. The data yield superlattice periods of 18.0 and 12.1 nm. The optical phonon energies are observed to be different from bulk values.

    We observe that the energy of the GaSb longitudinal optical phonons in GaSb-AlSb superlattices is about 2 cm-1 lower than in bulk GaSb. We show that this effect is fully explained by the consideration of the misfit strains which are known to exist in these superlattices. This shift of the Raman...

    We observed a violation of the normal Raman selection rule in the resonant Raman spectra of interface (IF) phonon modes of the ultrathin (GaAs)[sub 4]/(AlAs)[sub 2] superlattice. Contrary to the prediction of conventional theories, all four IF modes were observed in both (XX) and (XY)...
