Technology - epitaxial graphene on silicon carbide

They will move around via surface diffusion and will finally rearrange in a pattern that is given by an energetically driven surface reconstruction. The resulting lattice constant is commensurate to that of graphene and therefore it is said that graphene grows epitaxially. This has been confirmed only for graphene grown on the Si face of SiC.
