Detailed knowledge of metal-carbon interactions is indispensable for generating graphene-based nanostructures for application in catalysis, electrodes, and magnetic storage. Graphene has been grown on many transition metal surfaces by chemical vapor deposition, where the layer forms a moiré superstructure owing to the mismatch between the lattice constants of graphene and those of the underlying metal surface. Such moiré patterns have been used as templates to grow uniformly sized metal clusters. In this work, we studied the interaction of Ag atoms with graphene supported on Rh(111) by using a scanning tunneling microscope (STM). Because of their unique localized plasmon response, Ag nanoclusters have been studied as optical materials. Therefore, we also investigated the correlation between the structure of Ag clusters and their optical properties.
