A theoretical study of InSb based on the effect of van der Waal’s interactions (VDWI) and three-body interactions (TBI) into the rigid shell model (RSM) of zinc blende structure (ZBS). The van der Waal’s three body shell model (VTSM) is performed to analyze the phonon dispersion curves, Debye temperatures variation, combined density of states (CDS) curves, two-phonon Raman and anharmonic elastic properties, where the short range interactions are operative upto the second neighbours. Our results are reasonably good agreement observed between theoretical and experimental data.
