X-ray photoelectron spectroscopy of low surface concentration mass-selected Ag clusters
(2000) In Journal of Chemical Physics 113(20). p.9233-9238- Abstract
Low surface concentrations of mass-selected clusters deposited under ultra high vacuum conditions on a well-characterized surface were studied with XPS. Analysis of monomers and dimers deposited at low temperature in a thick Xe buffer layer indicates the mobility and aggregation of the clusters in such a film. A stable average cluster size is reached at 53 K that is likely to be the same for all initially deposited cluster sizes studied in the range Ag1-Ag5. Cluster aggregation progresses as the temperature is raised, tending toward the formation of metallic islands at high temperatures.
