Nanotubes beat metal wires, reach 10 GHz

From a UC Irvine press release, based on work published in Nano Letters: UC Irvine scientists have demonstrated for the first time that carbon nanotubes can route electrical signals on a chip faster than traditional copper or aluminum wires, at speeds of up to 10 GHz…Now that Burke’s team has developed both high-speed nanotube-interconnect technology and high-speed nanotube-transistor technology, they hope to integrate the two into an ultra-high-speed all-nanotube electronic circuit, faster than any existing semiconductor technology.
