摘要
The applicability of density-functional theory is extended to physisorption at surfaces by a proposal for the form of the long-range nonlocal exchange-correlation functional E(xc). The functional is applied successfully to physisorption of He, Be, and H-2 on jellium and of H-2 on the low-indexed faces of Al.
