When silicon carbide is heated to 2000 C, silicon atoms on the surface moves to the vapor phase and only the carbon atoms remain. The graphene does not react easily with its surroundings due to the high quality of the graphene layer and its innate inertness, while appliions often rely on controlled interaction between the material and the surroundings, like gas molecules.

Sublimation of carbon atoms on a silicon carbide substrate results in high quality graphene films, however the main drawbacks are the high cost and limited size of the substrate. CVD growth offers a good compromise between film quality, size, and cost.

Abstract. Graphene on silicon carbide (SiC) bears great potential for future graphene electronic appliions because it is available on the wafer scale and its properties can be custom tailored by inserting various atoms into the graphene/SiC interface. It remains unclear, however, how atoms can cross the impermeable graphene layer during this

Silicon Carbide is a widely used material in the field of electronics. By sublimating the atoms of Si, the remaining face of the SiC has a graphite surface. Nowadays the nuer of layers of graphene could be controlled and the quality is very high over a wide area (crystallites of some hundreds of micrometers ).
