Abstract: Intercalation of the graphene-cobalt system with silicon was investigated experimentally. The ab initio calculation of the electronic structure of a low-dimensional graphene-silicon-cobalt system was carried out using the density functional theory. The most advantageous positions of intercalated Si atoms are determined. It is shown that the introduction of silicon under graphene leads to a sharp decrease in the interaction of carbon atoms with the substrate.
Keywords: graphene, intercalation, cobalt silicides, DFT calculations, thin films, photoelectron spectroscopy.
