✦ Synopsis

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