Claim 0:
1. A method for forming graphene, said method comprising:
scavenging, in presence of a substrate gas scavenging composition and a scavenging temperature, a substrate sheet to produce an at least partially contamination-depleted surface;
annealing, in presence of an annealing gas composition and an annealing temperature, said substrate sheet having said at least partially contamination-depleted surface to produce an annealed surface;
producing graphene, in presence of a producing composition and a producing temperature, on said substrate sheet having said annealed surface to produce a graphene deposited surface; and
cooling, in absence of an active heat source disposed adjacent to said substrate sheet and in presence of said substrate gas scavenging composition, said substrate sheet having said graphene deposited surface to produce a relatively cool surface.
