摘要：

Based on the empirical pseudopotential method (EPM) modified with virtual crystal approximation (VCA), we report a detailed study of the pressure dependence of the phonon frequencies, sound velocity, and Debye temperature of AlxIn1-xPy Sb1-y alloys lattice-matched to GaSb, InAs, and InP substrates. There is a good agreement between our calculated results and the available data in the literature for the constituent's binary compounds which gives support for those of the studied alloys. The phonon frequencies and sound velocity are increased nonlinearly by enhancing pressure and giving high results for the InP substrate than those of other substrates. The results in this work seem likely to be useful as a reference that we report for the first time.
