Nanotube Electronics: IBM makes full transistor circuit with a carbon nanotube

A functioning processor on a carbon nanotube has been created by IBM scientists, offering the possibility of terahertz processors in hybrid nanotube silicon devices in 5-10 years. The IBM researchers created a type of logic device called a ring oscillator. It consisted of 12 bi-metal field effect transistors laid along the 18 micrometre length of the nanotube.
