In a method of producing ultra-thin graphitic layers, a carbide crystal is placed into a graphitic enclosure. The carbide crystal and the graphitic enclosure are placed into a chamber. The carbide crystal and the graphitic enclosure are subjected to a predetermined environment. Once the predetermined environment is established, the carbide crystal and the graphitic enclosure are heated to a first temperature for a predetermined period of time sufficient to cause at least one non-carbon element to evaporate from a crystal face of the carbide crystal so as to form at least one graphitic layer on the crystal face of the carbide crystal.

Method and apparatus for producing ultra-thin graphitic layers

In a method of making a functionalized graphitic structure, a portion of a multi-layered graphene surface extending from a silicon carbide substrate is exposed to an acidic environment so as to separate graphene layers in a portion of the multi-layered graphene surface. The portion of the multi-layered graphene surface is exposed to a functionalizing material that binds to carbon atoms in the graphene sheets so that the functionalizing material remains between the graphene sheets, thereby generating a functionalized graphitic structure. The functionalized graphitic structure is dried in an inert environment.
