Claim 2:
3. The method for forming graphene of claim 2, wherein said pretreating range of lateral distance including an initial pretreating lateral location or region and, disposed a lateral distance away therefrom, a subsequent pretreating lateral location or region,
wherein said exposing includes using one or more heat sources extending said pretreating range of lateral distance and being disposed adjacent to said surface such that said initial pretreating lateral location or region, inside said enclosure, is at a minimum temperature of an annealing temperature, and said subsequent pretreating lateral location or region, inside said enclosure, is at a maximum temperature of said annealing temperature, and
wherein said subjecting includes using multiple gas distribution systems that deliver to lateral locations extending said pretreating range of lateral distance such that a relatively low incident flow rate of a substrate gas scavenging composition is applied to said surface at said initial pretreating lateral location or region, and a relatively high incident flow rate of said substrate gas scavenging composition is applied to said surface at said subsequent pretreating lateral location or region.
