- Аннотация: A graphene coating deposited onto a copper substrate was irradiated with helium and argonions with an energy of 100 keV. The effect produced by the radiation fluence on the structure of a graphenecoating was studied by Raman light scattering. The processes of defect formation in a graphene coatingwas modeled at different ion irradiation parameters by the Monte Carlo method in the approximation ofbinary collisions. It has been shown that the transition to the displacement per atom parameter providesthe possibility to compare defect formation processes in a two-dimensional target at different irradiationparameters. It is demonstrated in this study that the accumulation of point defects occurs in a graphenecoating under irradiation until the displacement per atom parameter becomes close to 5 × 10−4, afterwhich the defect domains are joined with further coating structure destruction at a displacement per atomparameter ranged within 5 × 10−3−10−2.
