Abstract

A calculation of the surface phonon dispersion curves of Al(001) based on the density functional perturbation theory reveals the intrinsic nature of the controversial longitudinal surface phonon resonance, which has been reported to occur in most metal surfaces. The results support previous density response calculations by Franchini, Bortolani, et al as well as the nalysis based on the multiple-expansion model.
