The image potential in the weighted-density approximation

  • Note Brevi
  • Published:
Il Nuovo Cimento D

Summary

We analyse the image potential of a metal surface in the weightede-density approximation and obtain an analytical expression for the position of the image plane which is independent of the surface electronic structure. We conclude that the position of the plane image given by this density functional approximation cannot be accepted as a physical result.
