Abstract
We present data obtained with inelastic X-ray scattering measurements of th e phonon dispersions in hexagonal aluminum nitride along all three high-sym metry directions. These are the first such data for AIN. Presently availabl e single crystals are large enough to perform an inelastic X-ray scattering experiment. The results are compared with first-principles calculations. W e find excellent agreement between the data and the calculations.
