Abstract
A system and method for producing graphene includes a discharge assembly and a substrate assembly. The discharge assembly includes a cathode and an anode, which in one embodiment are offset from each other. The anode produces a flux stream that is deposited onto a substrate. A collection device removes the deposited material from the rotating substrate. The flux stream can be a carbon vapor, with the deposited flux being graphene.
Claims18
A graphene producing device comprising:
- a substrate, a graphite cathode, a carbon anode, wherein said cathode and anode create an arc discharge producing a flux stream and are configured to deposit material from the flux stream on said substrate.
A method for synthesizing graphene, the method comprising:
- providing a substrate;
- providing a first electrode;
- and
- providing a second electrode offset from the first electrode, said second electrode producing a flux that is deposited onto the substrate.
