Abstract
First-principles calculations are performed to investigate dynamical and di electric properties of group-III-nitrides. We focus on vibrational frequenc ies, dynamical charges, and the phonon density of states of cubic AlN, GaN, and InN. Chemical trends are derived and discussed. The first ab initio ca lculations of phonon branches and density of states are presented for an or dered InxGa1-xN structure.
