Zusammenfassung
Structural and lattice dynamical properties of sapphire are investigated within the framework of density functional perturbation theory. We obtain weak anisotropies in the dielectric tensor and in the Born effective charges. The theoretical phonon dispersions are found to be in very satisfactory agreement with available experimental data.
