Classification: CPC C  B | IPC B  C

Claim 13:
14. A method for forming graphene, said method comprising:
providing a continuous graphene formation system including an infeed portion having one or more infeed tunnels and a furnace portion having one or more processing sub-enclosures disposed laterally adjacent to said one or more infeed tunnels;
pretreating in said one or more infeed tunnels a surface for processing using a pretreating flowrate of a substrate gas scavenging gas composition, in presence of one or more pretreating temperatures, to produce a contaminant-depleted surface; and
treating in said one or more processing sub-enclosures said contaminant-depleted surface using a treating flowrate of an annealing gas composition, in presence of one or more treating temperatures, to produce an annealed surface.
