Abstract

High-resolution electron energy loss spectroscopy (HREELS) in reflection geometry was used to probe the surface of K ₃ C ₆₀ multilayer films as well as C ₆₀ ^3- monolayers adsorbed on Ag(1 1 1) and Cu(1 1 1). The -3 charge state of the adsorbed fullerenes was obtained by distilling K-saturated C ₆₀ monolayers. We found that roughly 2 electrons are donated by the K atoms on Ag(1 1 1) and slightly less than 1.5 electron in the case of Cu(1 1 1), the charge difference being provided by the metallic substrates. The surface of the K ₃ C ₆₀ multilayer films has a charge state of about -1.5 and is thus underdoped.
