The method of molecular dynamics has been used to study the bombardment of a copper film on graphene by Ar13 clusters with a kinetic energy of 20 eV and incident angles θ = 75°, 60° and 45°. The complete removal of copper from the graphene sheet was achieved only at the angle θ= 45°. In this case, the horizontal and vertical components of the self-diffusion coefficient of copper in the film have higher...
