Abstract—The behavior of single- and double-sided monatomic aluminum films on graphene heated from 300 to 3300 K is studied by the molecular dynamics method. Atoms of single-sided coating are preserved on graphene up to 3300 K, while atoms of double-sided coating leave graphene even at 1800 K; upon a further increase in temperature, this leads to an increase in the horizontal and vertical components of the self-diffusion coefficient. The stresses produced by vertical forces are found to be most significant in metallic films; these stresses almost disappear when temperature reaches 2300 K. The stresses in graphene, the highest of which are concentrated in the zone of formation of the metal film, substantially decrease upon heating.
