Abstract — By the molecular-dynamics technique, the authors have investigated the bombardment of a thin lead film on graphene by a beam of Xe clusters in the range of energies 5–30 eV at an angle of incidence of 45o. Visual observation and the density profile of the Pb film point to a complete separation of the film from graphene followed by the formation of a lead cluster during the bombardment with a cluster energy of 20 eV. Such bombardment leads to maximum horizontal and minimum vertical mobilities of C atoms in graphene and also generates a minimum stress in the film′s plane due to vertical forces.
