This paper presents direct growth approach for production of graphene and carbon nanotubes in an on-chip manner towards integrated devices. Vertically aligned arrays of carbon nanotubes and edge-oriented graphene are synthesized by microwave plasma-enhanced chemical vapor deposition using methane and hydrogen as precursors. Cyclic voltammetry (CV) and electrochemical energy impedance measurements with ferricyanide redox reaction reveal a fast electron transport and a low resistance of charge transfer of both carbon nanotubes and graphene.
