Silicon carbide (SiC), also known as carborundum / k ɑːr b ə ˈ r ʌ n d əm /, is a semiconductor containing silicon and carbon.It occurs in nature as the extremely rare mineral moissanite.Synthetic SiC powder has been mass-produced since 1893 for use as an abrasive..
Graphene has a negative thermal expansion coefficient; that is, when heated, the graphene lattice shrinks. On the other hand, the substrates typically used for graphene growth, such as silicon carbide, have a positive thermal expansion coefficient. Hence, on cooling graphene on SiC, graphene expands but SiC shrinks. This mismatch will physically break the atomic bonds between graphene and SiC

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.
