Claim 8:
9. The method for forming graphene of claim 8, wherein said passivating range of lateral distance including an initial passivating lateral location or region and, disposed a lateral distance away therefrom, a subsequent passivating lateral location or region,
wherein said exposing includes using one or more heat sources extending said passivating range of lateral distance and adjacent to said surface such that a substantially constant annealing temperature is provided at locations extending said passivating range of lateral distance inside said enclosure, and
wherein said subjecting includes using one or more gas distribution systems for applying a relatively high incident flow rate of a substrate gas scavenging composition to said surface at said initial passivating lateral location or region and applying a relatively low incident flow rate of said substrate gas scavenging composition to said surface at said subsequent passivating lateral location or region.
