Molecular-dynamics study of the interaction between energetic Al clusters and an Al surface

Abstract

We have investigated the approximate transient temperature and transient time as a function of cluster size in the case of the same total energy and in the case of the same energy per atom. The approximate transient temperature was directly proportional to both energy per atom and total cluster energy. In the case of the same energy per atom, since the correlated collisions rapidly transferred energy to the substrate, the transient time was approximated by a constant value as the cluster size increased. The correlated collisions play an important role in the interaction between an energetic cluster and the surface, affecting their interaction as the size and energy of the cluster increases.
