1. A system for forming graphene, said system comprising:
a substrate holder designed for holding a substrate sheet;
one or more outfeed tunnels disposed adjacent to said substrate holder;
multiple processing sub-enclosures disposed laterally adjacent to one or more said outfeed tunnels such that said substrate holder continuously laterally extends from inside one or more said multiple processing sub-enclosures into said outfeed tunnels;
multiple outfeed gas outlets disposed inside one or more said outfeed tunnels, wherein at least some of said outfeed gas outlets are oriented in a direction that is parallel to said substrate holder and designed to generate a laterally flowing scavenging gas stream that removes contents inside one or more said outfeed tunnels; and
multiple gas distribution subsystems communicatively coupled, at one end, to one or more reservoirs of same type of components that form a producing composition and/or a substrate gas scavenging composition, and communicatively coupled, at another end, to at least one said processing sub-enclosures and wherein multiple said gas distribution subsystems designed to dispense or produce said producing composition and/or said substrate gas scavenging composition inside at least one said processing sub-enclosure; and
wherein, in absence of an effective gas or a mechanical barrier within and between one or more said outfeed tunnels and at least one said processing sub-enclosure, said system for forming graphene is designed to allow heat and said producing composition and/or said substrate gas scavenging composition present inside at least one said processing sub-enclosure to laterally flow into and be removed from said outfeed tunnels.
