Abstract

A three body interaction potential (TBIPZpe) model is developed to study the structural phase stability of SrS having NaCl (B1) structure at room temperature. This model consists of long range Columbic, three body interaction forces, short range overlap forces operative up to next nearest neighbors and zero point energy effects. We have reported the phase transition pressure, volume collapse and second order elastic constants and found results well agreed with available experimental data.
