Regularities of intercalation of two-dimensional graphite films on metals by atoms and C60 molecules

This article is a brief review devoted to the intercalation of two-dimensional graphite films (2DGFs) on metals. It is shown that two types of intercalation of atoms into 2DGF depending on the ionization potential of the intercalate can take place, and regularities of both are described. A new physical picture for the mechanism of the intercalation process is proposed and described in detail. A new unusual result, the possibility of intercalation of C60 molecules into 2DGF, is reported. C60 molecules are shown to stay without disintegration up to 1200 K in contact with the iridium surface.
