摘要：
First-principles calculations are performed to investigate dynamical and dielectric properties of group-III-nitrides. We focus on vibrational frequencies, dynamical charges, and the phonon density of states of cubic AlN, GaN, and InN. Chemical trends are derived and discussed. The first ab initio calculations of phonon branches and density of states are presented for an ordered InxGa1−xN structure.
