Simple theory of elastically deformed metals: Surface energy, stress, and work function
Abstract
The effect of uniaxial strain on surface properties of simple metals is considered within the stabilized jellium model. The modified equations for the stabilization energy of the deformed WignerSeitz cells are derived as a function of the bulk electron density and the given deformation. The model requires as input the density parameter r_{s}, the Poisson ratio, and Young's modulus of the metal. The results for surface energy, surface stress, and work function of simple metals calculated within the selfconsistent KohnSham method are also presented and discussed. A consistent explanation of the independent experiments on stressinduced contact potential difference at metal surfaces is given.
