Electron density of metallic surfaces by variation method

  • Published:

Abstract

In this paper variational calculation is performed for simple jellium metal surface electron density using the density functional theory. A trial function of the local electron density is proposed. The free parameters are obtained by minimization of the total energy functional. The effect of the high density gradient expansions of the kinetic emergy is studied (i.e. Kirzhnits energy). The results obtained are similar to those of Lang and Kohn, which use a more exact method.
