Researchers from UC Santa Barbara (UCSB) developed a new scalable method to synthesize high-quality and high-uniformity graphene (both mono-layer and bi-layer).

The team method is based around the graphene's growth kinetics under the influence of the substrate. Their approach uses a method called low pressure chemical vapor deposition (LPCVD) and involves disintegrating the hydrocarbon gas methane at a specific high temperature to build uniform layers of carbon (as graphene) on a pre-treated copper substrate.
