Abstract

The optic phonons of Ga_1-xAl_xSb layers with 0=x=1 grown by molecular-beam epitaxy on GaAs and GaSb substrates have been studied using Raman spectroscopy. The phonon energies are interpreted using a modified random element isodisplacement model to allow accurate composition determination. A comparison between the layers grown on GaAs and GaSb substrates is made in terms of strain and anharmonicity effects and related to x-ray and transmission electron microscopy measurements.
