CVD Graphene on Copper Graphic (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption To make a graphene thin film, Berkeley researchers (a) evaporated a thin layer of copper on a dielectric surface; (b) then used CVD to lay down a graphene film over the copper. (c) The copper dewets and evaporates leaving (d) a graphene film directly on a dielectric substrate.
