Abstract
Self-consistent full-potential linear muffin-tin orbital calculations of the electronic structures are used to investigate the optical phonon modes and their behavior under hydrostatic pressure. The calculations are performed for AlN and GaN in the wurtzite and zinc-blende structures. The calculated phonon frequencies and their pressure coefficients agree well with experimental results, best in the case of GaN.Keywords
