Mechanical Properties and Acoustic Velocity for Nanostructured AlxIn1-xPySbzAs1-y-z Alloy Under the Impact of Pressure

Abstract The mechanical properties of AlxIn1-xPySbzAs1-y-z alloy under the impact of pressure have been studied. Also, the acoustic velocity of AlxIn1-xPySbzAs1-y-z alloy under the influence of pressure has been investigated. Calculations have been made for the considered alloy lattice matched to the InP substrate. The empirical pseudopotential method with the virtual crystal approximation was used. The stability requirements, which depend on the elastic constants found at different pressures, evaluate the mechanical stability under the pressures. There is good agreement between the calculated results and the available experimental data. The calculated results can be used in optoelectronic applications under high-pressure values.
