March 3, 2008 — Fujitsu Laboratories Ltd. has formed a new nanoscale carbon composite featuring a self-organizing structure by combining carbon nanotubes and graphene, the company says.

The new composite is synthesized at a temperature of 510 °C, cooler than for conventional graphene formed at temperatures too high for electronic device applications, paving the way for the feasible use of graphene in electronic devices.

Carbon nanotubes have properties including high thermal conductivity and high current-density tolerance, while graphene is known for its high electron mobility. Carbon nanostructures combining these two materials hold the promise of creating new potential for material research and applications.

Details of this technology will be presented at the 34th Fullerene Nanotubes General Symposium March 3-5 in Nagoya, Japan.
