Formation of Nanocomposites on the Surface of Silicon Carbide Crystals under Impact of Iron Fluxes

The formation of graphene–iron composite structures on the surface of cleavages of silicon carbide single crystals using vacuum thermal destruction with simultaneous deposition of iron atoms has been investigated. The effect of the iron deposition rate on the formation of single- and multilayer graphene structures is established. It is shown by X-ray photoelectron and Raman spectroscopy that iron partially dissolves in the graphene structures without formation of nanocrystallites, clusters, etc.
