Carbon nanotubes are graphene tubes that have a diameter measured in nanometers. Single-wall carbon nanotubes with sizes in the nanometer range are usually referred to as carbon nanotubes. Carbon nanotubes with a single wall are an allotrope of carbon which lies halfway between fullerene cages and flat graphene. Carbon nanotubes are also known as multi-wall carbon nanotubes, that are made up of nested single-wall carbon nanotubes that are weakly bound together in a tree ring-like structure by van der Waals interactions. Although some carbon nanotubes are conductive, others are semiconductors. Because of their nanostructure and the strength of the bonds between carbon atoms, they have exceptional tensile strength and thermal conductivity. All achiral single-wall carbon nanotubes are either tiny or moderate band gap semiconductors, with the exception of a small group of metallic nanotubes.
