IBM builds nanotube chip

IBM researchers have achieved a milestone by creating an integrated circuit out of a single carbon nanotube, a feat that makes the material a likely candidate to replace silicon as the main ingredient for making chips.

Long thought to be a good candidate for replacing silicon, carbon nanotube has posed great challenges for scientists who try to coax transistors out of the material and create an integrated circuit (IC).
