Abstract
Methods and apparatuses for forming a graphene film, and graphene films produced thereby. A method of forming a graphene film includes depositing a carbon source onto a substrate within a deposition environment including a vacuum to form the graphene film on the substrate. The carbon source includes coal, a coal component, or a combination thereof
Claims20
A method of forming a graphene film, the method comprising:
- depositing a carbon source onto a substrate within a deposition environment comprising a vacuum to form the graphene film on the substrate, wherein the carbon source comprises coal, a coal component, or a combination thereof.
A graphene film comprising a CVD-deposited carbon source, the carbon source comprising coal, a component extracted from coal, or a combination thereof
An apparatus comprising:
- a chemical vapor deposition unit comprising a deposition environment;
- and
- an injector unit that is configured to inject a carbon source entrained in a gas into the deposition environment for deposition on a substrate and formation of a graphene film thereon, the carbon source comprising coal, a coal component, or a combination thereof.
