Abstract
A method of forming graphene includes placing a substrate in a processing chamber and introducing a cleaning gas including hydrogen and nitrogen into the processing chamber. The method also includes introducing a carbon source into the processing chamber and initiating a microwave plasma in the processing chamber. The method further includes subjecting the substrate to a flow of the cleaning gas and the carbon source for a predetermined period of time to form the graphene.
