摘要：

By using embedded-atom-method interatomic potentials and molecular-dynamics simulations, we study the collision of a single Ag-7 cluster on the Pd(100) substrate, at impact energies in the direction perpendicular to the (100) surface E(1)=20 eV (2.86 eV/atom) and E(2)=95 eV (13.6 eV/atom). Our results indicate that implantation occurs at both impact energies, but it is more important at E(2). AS opposed to what is shown experimentally, little fragmentation takes place for E(1), while the calculated cluster fragmentation is in good agreement with the experimental data for E(2).
