cylinders as small as 1 nm in diameter grown from fullerenes to resemble a rolled-up sheet of graphite; exhibits desirable semiconductor characteristic such as ballistic electron transport, plus is structurally 100 times stronger than steel of the same weight
A cylinder-shaped structure resembling a rolled-up sheet of graphite that can be a conductor or semiconductor depending on the alignment of its carbon atoms. It is 100 times stronger than steel of the same weight, although due to high fabrication costs, widespread commercial use is still distant.

One of the most important materials of nanotechnology, a nanotube is a kind of molecule made of a lattice of carbon atoms. The cylindrical structure not only is light and strong, but also has superconducting properties that let it transmit electricity with no energy loss.
Single-wall carbon nanotubes (SWCNTs) can be considered to be formed by the rolling of a single layer of graphite (called a graphene layer) into a seamless cylinder. A multiwall carbon nanotube (MWCNT) can similarly be considered to be a coaxial assembly of cylinders of SWCNTs. Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites. At the moment this material is still very expensive since it must be \"grown\" but it is expected that it will make its F1 introduction in the next few years.
Carbon nanotubes (CNTs) are an allotrope of carbon. A carbon nanotube is a one-atom thick sheet of graphite (called graphene) rolled up into a seamless cylinder with diameter of the order of a nanometer. This results in an essentially one-dimensional nanostructure where the length-to-diameter ratio exceeds 10,000.
