摘要
The formation of thin films by deposition of size-selected platinum and gold clusters on graphite surfaces is analyzed. By precise adjustments of the environment of the clusters, their size, and their nature, the cluster reactivity is evidenced as a parameter to control thin-film morphologies. Thus, by adjusting the kinetics of species adsorption (likely CO) on the cluster surface, one can avoid coalescence between neighboring clusters on the substrate and induce a local spontaneous organization of size-selected clusters.
