The calculations for variations of bulk modulus $(B)$, compression volume $\Big(\frac{V_p}{V_o} \Big),$ 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.
Keywords: equation of state, Bulk modulus, lattice parameter, phonon frequency spectrum.
