Abstract
In this article we calculate the asymptotic structure of the exchange potential for the Fermi level electron in the vacuum region outside a metal surface, and show it to be the image potential. In this asymptotic region the exchange potential due to the Fermi level electron is equivalent to the optimized potential of exchange-only density-functional theory. Thus, the asymptotic Kohn–Sham effective potential at a metal surface is the image potential, and arises soley due to correlations which result from the Pauli exclusion principle. © 1993 John Wiley & Sons, Inc.
