Manufacturing graphene
At PTB, a manufacturing procedure for monolayer graphene has been developed to produce a quantum standard for the electric unit of resistance. Thanks to its reliability and simplicity, this enhanced multi-step sublimation method allows the production of large-scale graphene structures. This also paves the way for the mass production of qualitatively highend monolayer graphene films. The produced samples of 10 mm × 5 mm exhibit no irregularity in their material as may occur due to the formation of multiple layers of graphene or due to high substrate steps.
