(a) A representative network of simulated graphene sheets in a nanocomposite. The darker shaded regions at either end indicate source/drain electrodes. (b) Resistivity as a function of graphene sheet volume fraction, observing the characteristic inverse power law behavior of percolation systems. The device dimensions are in width, in length, and 30 nm in thickness with sheet areas of . The vertical line represents the location of the critical volume fraction .
