Abstract

The surface energies of W(001) and V(001) are determined theoretically within local-density-functional theory employing the all-electron full-potential linearized augmented-plane-wave method. The calculated values are 5.1 J/m2 for W(001) in good agreement with experiment and 3.4 J/m2 for V(001). Multilayer surface-relaxation calculations show that the surface-relaxation energy is small and amounts to only a few percent of the surface energy. The surface entropy at sufficient high temperatures for the W(001) surface, as deduced from a comparison of our calculated result and high-temperature experimental surface-energy values, is large (1.5×10-3 J/m2 deg).
