Abstract: A method for use in the synthesis of graphene is described that comprises the steps of annealing a substrate in a hydrogen gas atmosphere, subsequently undertaking a deposition and nucleation step in which a relatively thick carbon layer is deposited onto the substrate and subsequently thinned to form small graphene islands or nuclei, undertaking a graphene growth step in which the graphene islands or nuclei expand and coalesce, and subsequently allowing the substrate to cool. A sensor 10 incorporating the graphene sheet is also described.
