Abstract

Carbon nanotubes are unique tubular structures of large length/diameter ratio and nanometer diameter. CNTs possess extraordinary electric properties and they have capacity to carry an electric current 1000 times better than copper wires. Pressing or stretching nanotubes can change their electrical properties by changing the quantum states of the electrons in the carbon bonds. These single crystal structures can exhibit either semiconducting or metallic behaviour depending only on the diameter and angle of lattice. This paper is intended to summarize some of the major properties and applications of carbon nanotubes.
