Abstract
This talk describes an extensive computer simulation investigation of the structure, thermodynamics and phase stability of Lennard-Jones clusters adsorbed onto a surface, with special emphasis on the cluster melting regime. This investigation includes molecular dynamics simulations of the solid-like and liquid-like phases of the Lennard-Jones 13-atom cluster, of the melting and desorption process, evidence of surface wetting and mobility of the atoms within the cluster. We conclude that solid-like phase changes and wetting take place in these finite size systems and both phenomena are dependent on the ratio substrate/atom-atom interaction.KeywordsMetastable StateCoexistence RegionMicrocanonical EnsembleIcosahedral StructureFree ClusterThese keywords were added by machine and not by the authors.
