Opinion: Complex Nanotube Circuits
1) Grow the nanotubes on a separate substrate, then stamp them onto the circuit. This lets the circuit stay at low temperatures. By contrast, nanotubes are single, precise molecules being assembled to build up useful larger systems. This is a lot closer to the original meaning of the word.
