Abstract

The interaction between energetic clusters of atoms and solid surfaces has been investigated by molecular-dynamics computer simulation. In this model, the impact of Cu clusters containing 4, 13 or 92 atoms and energies of 326 eV with Cu or Ni substrates is investigated. Either embedded-atom-method (EAM) potentials or a combination of Moliere and EAM potentials were employed for the calculations. The simulations reveal that different physical processes occur depending on cluster size and energy, and the cohesive properties of the substrate.
