NOVELTY - Forming graphene involves pretreating a surface for processing using one or more pretreating flowrates of a substrate gas scavenging gas composition and/or an annealing gas composition, in presence of one or more pretreating temperatures, to produce a contaminant-depleted surface, and treating contaminant-depleted surface using one or more treating flowrates of annealing gas composition, in presence of one or more treating temperatures, to produce an annealed surface. USE - Method for forming graphene. ADVANTAGE - The method effectively and continuously producing graphene inside a single, continuous, and laterally extending chamber.
