Summary on Grant Application Form |
|
We propose detailed experimental (STM) studies of the deposition and diffusion of size selected metal (eg Au, Ag) clusters on metal surfaces (eg Pt(111), Au(110)) and graphite. The experiments will employ a mass-selected cluster beam source together with a novel low temperature UHV STM for in situ studies of cluster deposition, diffusion and thin film growth as a function of cluster size, kinetic energy, deposition rate and surface temperature. The experiments will shed light on the basic processes occurring in the cluster-surface impact as well as the mechanisms of diffusion and growth on the surface. We also propose to investigate the deposition and growth modes of size-selected metal clusters at surface steps (eg on graphite); diffusion of clusters to the steps and preferential adsorption there is expected to produce cluster wires . The structural studies of the clusters will be complemented by spectroscopic measurements of the cluster plasmons with high resolution electron energy loss spectroscopy (HREELS). Deposition of mass-selected clusters on surfaces underpins a wide range of potential application of cluster-based thin films .
