Abstract
The lattice dynamics of wurtzite GaN and AM is studied within the framework of a rigid-ion model. Short-range interactions up to the third nearest nei ghbors are described by using a valence-force-field potential and the long- range Coulomb interactions between ions are calculated via. an Ewald summat ion. Phonon dispersion curves, density of states and specific heats are pre sented.
