Abstract:We review theoretical treatments of physisorption of Xe on Cu(111) and Pt (111) surfaces within the recently proposed extended density functional approach that explicitly takes into account the van der Waals interactions among the constituents of adsorption systems. Based on tests of the various currently used approximations for the density functionals, and of the different treatments of long-range correlation effects which we carried out for a prototype system of a Kr dimer, we have adopted in the present stu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
