The dependence of electronic band structure, optical phonon frequencies, acoustic velocities, and mechanical properties of InP1-xSbx alloys on temperature and pressure were analyzed in this study. The virtual crystal approximation (VCA) with the compositional disorder effect (CDE) was considered. Results showed good agreement with published values and may serve as reference for experimental work, providing insights for optoelectronic applications.
The dependence of electronic band structure, optical phonon frequencies, acoustic velocities, and mechanical properties of InP1-xSbx alloys on temperature and pressure were analyzed. The empirical pseudo-potential method (EPM) is performed to study the electronic structure and the mechanical properties for the considered alloys. The virtual crystal approximation (VCA) with the compositional disorder effect (CDE) is taken into account in this work. The influences of temperature and pressure on the optical phonon frequencies and on the acoustic velocities of the studied alloys have not been fully studied. So, we concerned on these properties under the influence of pressure and temperature. Good accord was obtained between our results and the available published values. Our findings may serve as reference for the experimental work. The studied properties of the considered alloys may give a helpful for the optoelectronic applications.
