Carbon nanotubes are hollow tubes made from single sheets of carbon atoms. Along the length of the tube they can be excellent electrical conductors, and they are also the stiffest known material. However, just like a drinking straw, they can be easily deformed or pinched in a radial direction. Attaching electrical contacts to the tube has always proved challenging -some contacts are good, others a thousand times worse. The first 3 Judy J. Cha and D. Muller (IRG"1)
