Mechanical, optical, and lattice vibrational properties of gallium antimonide (GaSb) semiconductor under the influence of temperature

Abstract

Abstract We have determined the optical, mechanical, and lattice dynamic features of the zinc-blende GaSb compound. It has been investigated how temperature affects longitudinal and transversal sound velocities, reflectivity, phonon frequencies, micro-hardness, and transverse effective charge. Additionally, the dependences of the effective charge, ionicity, bending, stretching force constants, susceptibility, Cauchy, and Born ratios on the temperature of zinc-blende GaSb material, have been calculated. The pseudo-potential method (EPM) has been used to perform the computations in this paper. Comparative analysis with the existing experiment and other theoretical calculations reveals a respectable degree of agreement.
