| Popis: | This paper discusses a novel deposition route of size-selected metal clusters, specifically AgN+ (where N = 2700), on graphite. The clusters are produced via a magnetron sputtering, gas aggregation cluster beam source and are size selected via a lateral time-of-flight mass filter. These clusters are deposited on a highly oriented pyrolytic graphite (HOPG) target predecorated with surface defects via Ar+ sputtering. Scanning tunnelling spectroscopy (STM) reveals a stable, randomly dispersed array of Ag2700 clusters after deposition. |
