摘要：

The problem of developing a nondestructive method for purification of graphene to remove a deposited metal has been tackled. Bombardment of copper film-precoated graphene by argon clusters has been simulated in terms of molecular dynamics. With a flow of 30-eV clusters directed parallel to the graphene sheet plane, the full removal of copper from graphene is achieved. The mobility of Cu and C atoms, the distribution of a stress that is the most susceptible to cluster impact in the graphene plane, and the graphene sheet surface roughness during the simulated process have been determined.
