Theoretical high pressure study for evaluation of spinodal pressure and phonon frequency spectrum of silver

Abstract EN

Compression versus pressure at room temperature has been evaluated for silver using different equations of states (Birch-Murnghan and modified Lenard-Jones EOSs).

A good agreement with experimental data has been observed.

Extrapolation of variation of bulk modulus results with pressure has been used to evaluate spinodal pressure.

The effect of high pressure on lattice frequency and phonon frequency spectrum (pfs) has been calculated too.

A comparison of the present, pfs results show a good agreement with the results of other theoretical published work
