Abstract
This Letter presents an approximate closed-form solution to the density-functional theory for the surface tension and surface width of simple liquids. The results for both are in excellent agreement with experiments on Ar over wide range of temperature and density. The theory is extended via an ion density-functional formalism to simple metals. Good agreement is obtained for the surface tensions of ten liquid metals and for the surface width of liquid Hg.Keywords
