Graphene production techniques - Wikipedia

2020-7-30 · Heating silicon carbide (SiC) to high temperatures (> 1100 °C) under low pressures (~10 −6 torr) reduces it to graphene. This process produces epitaxial graphene with dimensions dependent upon the size of the wafer. The polarity of the SiC used for graphene formation, silicon- or carbon-polar, highly influences the thickness, mobility and carrier density.
