原始语种摘要: Abstract(#br)We investigate a system consisting of Au nano-clusters and amorphous carbon (a-C) via core-level photoemission. While the ability of photoemission to characterize nano-sized metal clusters is well-known, still some issues deserve investigation. For example, the well-established dominance of final-state relaxation effects in core-level spectra from nano-clusters necessarily involves a crucial role of the cluster dielectric-environment. To the best of our knowledge however, a thorough discussion on this point is lacking. We thus intend to investigate dielectric-environment effects by considering several configurations for Au clusters, i.e. supported and embedded, with the latter obtained either by depositing a-C on top of supported clusters or by co-depositing a-C and Au. We...
