Influence of pressure and temperature on mechanical and thermal behaviors of InAsSb and GaAsSb alloys

Abstract

We have performed the first-principles calculations using the Density Functional Theory (DFT) and the empirical pseudopotential method (EPM) to study the fundamental behaviors of the InAsSb and GaAsSb semiconductors. The mechanical behaviors of InAsSb and GaAsSb alloys were calculated. Also, the thermal behaviors of InAsSb and GaAsSb alloys were investigated. We examined the impacts of pressure and temperature on the mechanical and thermal behaviors of the considered alloys. The mechanical and thermal behaviors of the InAsSb and GaAsSb alloys for composition (x = 0.5) under the influence of pressure and temperature haven’t been completely explored in the literature. Thus, we were interested in these behaviors under the pressure and temperature effects.
