A noncentral second neighbour ionic model is proposed for calculating frequency wave vector dispersion relations for the normal modes of vibrations for zinc and cadmium tellurides crystallizing in the zinc blende structure. The model takes into account the change in energy owing to rotation of bonds. The calculated phonon frequencies show a reasonably satisfactory agreement with the available optic data.

A first-principles plane-wave method with the ultrasoft pseudopotential scheme in the framework of density functional theory is performed to calculate the lattice parameters, the bulk modulus B0 and its pressure derivative B0' of the zinc-blende GaAs (ZB–GaAs), rocksalt GaAs (RS–GaAs), CsCl–GaAs, NiAs–GaAs, and wurtzite GaAs (WZ–GaAs). We also calculate the phase transition pressures between different phases, Debye temperatures, and the anisotropies. Our results are consistent with other theoretical results.
