Simulation of Impact Interaction of Uncharged Metallic Nanoclusters with Metallic Surface

Cover Page

Abstract


Investigation results of impact interaction of uncharged metallic nanocluster with metallic surface are presented. Simulation and investigations of impact processes are fulfilled by molecular dynamics methods and suitable software. Characteristic dimensions of surface layer produced by impact as a functions of cluster size, colliding energy and frequency of impulsive nanoclusters source have been analysed. It was found out that penetration depth and deposited layer thickness depend on number of particles in colliding nanoclusters and frequency of impulsive nanoclusters source. It was also discovered that deposited layer thickness in contrast to penetration depth ceases depending on number of particles in colliding nanoclusters N, and frequency of impulsive nanoclusters source ω and colliding energy E with increasing of N, ω and E. And at the same time deposited layer becomes heterogeneous in thickness and gets a funnel-shaped form. It is shown that realization of one of the choice of nanoclusters surface interaction (soft landing, droplet spreading and implantation) should be controlled by means of changing of both nanoclusters beam energy and number of atoms in clusters. Investigation results should be of interest in various fields of technologies developing nanomaterial with new physical and chemical properties.
