Abstract

A theoretical investigation of first order pressure induced structural phase transition, elastic and thermal properties of NdP compound has been carried out using the modified inter-ionic potential theory (MIPT), which parametrically includes the effect of coulomb screening. The calculated result of phase transition pressure (31 GPa) and elastic properties are agree well with the available theoretical and experimental data. We have also reported the second order elastic constants and Debye temperature of this compound.
