Size-Selected Monodisperse Nanoclusters on Supported Graphene: Bonding, Isomerism, and Mobility

Soft-landing of size-selected Pdn (n ≤ 20) nanoclusters on a Moire-patterned surface of graphene adsorbed on Ru(0001) leads to controlled formation of a truly monodisperse cluster-assembled material. Combined scanning tunneling microscopy and first-principles calcns. allow identification of selective adsorption sites, characterization of size-dependent cluster isomers, and exploration of interconversion processes between isomeric forms that manifestly influence cluster surface mobility. Surface-assembled cluster superstructures may be employed in nanocatalytic applications, as well as in fundamental investigations of phys. factors controlling bonding, structure, isomerism, and surface mobilities of surface-supported clusters.
