QuoteCarbon nanotubes, the reigning celebrity of the nanotechnology world, conduct electricity far better than metals. In fact, nanotubes exhibit what's called ballistic conductivity, which means that electrons are not scattered or impeded by obstacles. Nanotubes, which measure only a few billionths of a meter thick, are also far thinner than metal interconnects can be made. Potentially, this eliminates the problem with shrinking interconnects. IBM and others have made transistors out of carbon nanotubes. In its experiment, Intel aligned bundles of nanotubes by means of an electric field and then measured their frequency with fairly standard equipment.
