Abstract
The deposition of silver on a C-60 monolayer chemisorbed on Si(111) leads t o the formation of nanoscale clusters which, as determined from valence ban d photoemission measurements, donate minimal charge to the adsorbed fullere ne molecules. The low doping level of the C-60 monolayer leads to a slow ra te of Ag cluster neutralization following the emission of a photoelectron, resulting in a significant shift of the cluster Fermi level and valence ban d features to higher binding energy.
