Carbon NanotubeRLC Circuits

A new vision of carbon electronics is provided by the discovery reported here of carbon nanotube RLC (resistance–inductance–capacitance) circuits on nickel-sensitized alumina. When carbon nanotubes are deposited on an alumina surface by chemical vapor deposition from hydrocarbons, the electronic character of the nanotube/substrate combination depends on the preparation conditions. With development, this should allow RLC carbon nanotube microcircuits to be designed and deposited on substrates, perhaps even overcoming the difficulty of producing inductors in integrated circuits.
