Abstract

Although many phenomena in condensed matter Physics can be understood on the basis of a model, there are also considerable number of physical properties of solid which can not be explained except in the framework of lattice dynamics.We have calculated the PHONON FREQUENCIES of NACL, using an approach which is a combination of frozen phonon and force constants methods in the framework of density functional pseudo-potential theory. The dispersion relation curves were calculated along symmetry direction Δ, ∑ and Λ. We also calculated Grunesein parameters for all modes at X and L points in Brillion zone. The calculations are made in the framework of density functional and pseudo-potential theory, using super cell method, with the valence orbitals expanded in plane waves.
