Query: Density-functional theory of elastically deformed finite metallic
  system: work function and surface stress   The effect of external strain on surface properties of simple metals is
considered within the modified stabilized jellium model. The equations for the
stabilization energy of the deformed Wigner-Seitz cells are derived as a
function of the bulk electron density and the given deformation. The results
for surface stress and work function of aluminium calculated within the
self-consistent Kohn-Sham method are also given. The problem of anisotropy of
the work function of finite system is discussed. A clear explanation of
independent experiments on stress-induced contact potential difference at metal
surfaces is presented.
