Surface-phonon calculations for the Al(110) surface

The frequencies of surface modes at high-symmetry points of the surface Brillouin zone have been calculated with interplanar surface force constants determined from first-principles self-consistent total-energy calculations for the Al(110) surface. The multilayer relaxation for this surface produces...

Zusammenfassung:The frequencies of surface modes at high-symmetry points of the surface Brillouin zone have been calculated with interplanar surface force constants determined from first-principles self-consistent total-energy calculations for the Al(110) surface. The multilayer relaxation for this surface produces big deviations of the surface force constants from the bulk values. 24 ref.--AA(US).
