A simple approachfor the fabrication of graphene layers by self-limited oxidation of graphite flakes through a one-step annealing process is reported. Parallel graphene ribbons are readily formed by converting prepatterned graphite belts. This method indicates the feasibility of the controllable formation of graphene layers through control of the corresponding features of graphite flakes.
