Spherical Graphite And High Purity Graphite Production Process

Graphene production techniques Wikipedia

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
