[ODCAD] IBM: Nanotube Transistor, outperformed Si technology

Carbon nanotube can be used for many device application because of
its special electronic properties such as high electron mobility. IBM
developed a transistor based on C6 nanotube with the same drain,
source, gate and dielectric as Si CMOS technology, but using C6
nanotube instead of Si based semiconductor. The transistor has much
better performance than conventional one such as CMOS.

For IBM, and all of the industry, they still have manufacture
difficulties to massive produce the device.
