Or at least a new material for making diodes and chip material. How about an EFIS as thin as a wafer?

Nanotube sandwich your next carbon fibre aircraft. This is a very kool concept as nanotube weaving could cut the weight of your already light carbon aircraft and allow you to keep the strength and power.

NANOTUBES DETECT, REPAIR WING DAMAGE
Adding even a small amount of carbon "nanotubes" can go a long way toward enhancing the strength, integrity, and safety of composite structures, according to a new study at Rensselaer Polytechnic Institute, New York. Researchers there have developed a simple new technique for identifying and repairing small, potentially dangerous cracks in high-performance aircraft wings and many other composite structures. By infusing the polymer with electrically conductive carbon nanotubes and monitoring the electrical resistance at different points in the structure, Professor Nikhil Koratkar, who developed the method, can pinpoint the location and length of even the tiniest stress-induced crack.
Once a crack is located, Koratkar can then send a short electrical charge to the area in order to heat up the carbon nanotubes and in turn melt an embedded healing agent that will flow into and seal the crack. "What's novel about this application is that we're using carbon nanotubes not just to detect the crack, but also to heal the crack," Koratkar said. "We use the nanotubes to create localized heat, which melts the healing agent, and that's what cures the crack." To learn more, visit www.rpi.edu.
