The calculations for variations of bulk modulus (B), compression volume, lattice constant and phonon frequency spectrum (pfs) under high pressure up to 17 GPa at room temperature has been carried out. Three equations of state (EOSs) including (Birch-Murnaghan, Vinet and modified Lennard-Jouns) are used in the calculations. The variations of these properties under such high pressure for GaAs are obtained and we got suitable EOS for it.

Theoretical study was made on the high pressure dependence of lattice frequencies and distribution function for Gold through analyzing phonon frequency spectrum (pfs) by using Grüneisen approximation in two equation of state Birch-Murnghan (B-M EOS) and modify Lenard-Jones (mL-J EOS). The change in specific volume of crystal induce a change in the frequencies of lattice vibrations in a very complex manner. Present work shows how this complexity can be overcome by using Grüneisen approximation.
