▎ 摘　　要

The method of molecular dynamics has been used to study the removal of mercury from graphene by irradiating the target using a beam of Xe-13 clusters with energies of 5-30 eV at angles of incidence of 0A degrees, 45A degrees, and 60A degrees. The edges of the graphene sheet were hydrogenated. The complete removal of mercury from graphene was achieved at the angles of incidence of clusters equal to 45A degrees and 60A degrees with the energies of the beam E (Xe) a parts per thousand yen 15 and 10 eV, respectively. A substantial part of the film was separated from graphene in the form of a droplet. The form of the distributions of stresses in the graphene sheet indicates the absence of enhancement of the stressed state in the course of the bombardment. The bombardment at the angle of incidence of clusters equal to 45A degrees leads to the lowest roughness of graphene. As a result of the bombardments in the above ranges of energies and angles of cluster incidence, the hydrogenated edges of the graphene sheet did not suffer significant damage.
