(a) Illustration of two gate electrode configurations, planar and cylindrical, for a carbon nanotube and a Si FET. The radius of the nanotube is r, t is the thickness of the gate insulator, and h=t+r. A comparison is made between a silicon FET and an array of tubes with a minimum pitch of 4r and the same width as the Si FET. (b) Illustration of .
In 2013, a team at Stanford reported that it had arranged arrays of tiny, atom-thick cylinders to create an entirely new machine: the world's very first carbon nanotube computer.With a clock .
when testing carbon nanotube transistors. The Carbon Nanotube Transistor A single semiconducting CNT can be used as the conducting channel between the source and drain of a FET. Figure 1 illustrates a back-gated Schottky barrier CNT FET. Two metal contacts are located across both ends of the CNT to form the Source and Drain terminals of the FET.
