Lattice Vibration, Optical and Mechanical Properties of AlP Semiconductor under the Influence of Pressure

Abstract

The lattice vibrations, optical, and mechanical properties of zinc-blende AlP semiconductor have been investigated. Research has been carried out to determine how pressure affects various properties, including the refractive index, optical and static dielectric constants, longitudinal and transverse sound velocities, reflectivity, susceptibility, phonon frequencies, ionicity, transverse effective charge, and micro-hardness. The pseudo-potential method (EPM) was used to perform the computations in this article. A fair degree of agreement is seen when comparisons are made with the available experiment and other theoretical calculations.
