Molecular dynamic simulation of copper nanocluster deposition using graphics processing units (gpu)

In this paper, various aspects of the use of CUDA technology for solving molecular dynamics problems are considered. The complex of programs created on the basis of CUDA allowed to conduct a detailed study of the process of collision of a copper cluster with a metal substrate having a carbon film. It is established that cluster deposition is not observed if its fall rate is below the critical velocity for a given angle of incidence. A graphic relationship between the critical values ​​of the velocity and the angle of incidence of the cluster on the substrate surface is obtained.
