Abstract
Size selected metal oxide, sulfide and oxynitride clusters, soft-landed onto highly ordered pyrolytic graphite (HOPG) at room temperature, have been studied in this work. Based on their size and chemical compositions, the deposited clusters have exhibited various surface structures as illustrated by in situ Scanning Tunnelling Microscope (STM) and ex situ Atomic Force Microscope (AFM). In contrast to pure metal clusters, size selected metal compound clusters have shown different surface behaviours due to their different cluster-surface interactions.
