Electronic surface properties of alkali-metal alloys

Henryk Bogdanów, Kazimierz F. Wojciechowski

Abstract

A generalization of the stabilized jellium model (Perdew et al 1990, Phys. Rev. B 42 11 627) to random alkali-metal alloys is given and applied to calculations of the surface energy and the work function changes due to the concentration in the presence of surface segregation. The calculated variations in surface energy and work function against the concentration of the constituents are in good agreement with measurements.
