Carbon Nanotubes

Carbon nanotubes are cylindrical molecules that are composed entirely of carbon atoms. There are two types of carbon nanotubes: single-walled and multi-walled. Single-walled carbon nanotubes have widths close to one nanometer and lengths up to a few centimeters. These may be thought of as a single atomic layer of graphite (called graphene) rolled into a seamless cylinder. Multi-walled carbon nanotubes are basically several nanotubes stacked one inside another. For additional information visit www.nanotech-now.com
Here is an artistic vision of how carbon nanotubes can be connected to the molecular transistor , and serve as wires. To "see" how that would look in reality one needs to use special microscopy techniques.
