Structure of small Aun, Agn, and Cun clusters (n=2−4) on rutile TiO2(110): A density functional theory study

We examine the structure of small Aun, Agn, and Cun (n=2−4) clusters on rutile TiO2(110) surfaces using density functional theory calculations. Based on the comparison of supported and gas-phase clusters, we also discuss the effect of the cluster-substrate interaction on the atomic structure of small Au, Ag, and Cu clusters grown on TiO2(110).
