We have investigated the impact of small platinum dusters, Pt-3(-), on the surface of graphite for incident cluster energies in the range 50-1500 eV. The density of features observed in the STM rises markedly with increasing impact energy. Results for Pt-3(-) clusters and the lighter Ag-3(-) dusters can be overlaid, i.e. the feature density is independent of the cluster mass. This behaviour violates the binary elastic collision model for energy transfer to the substrate, but is consistent with recent simulations of the implantation of large clusters into the graphite surface.
