Carbon nanotube (CNT) is a new form of carbon,
configurationally equivalent to two dimensional graphene sheet rolled into a
tube. It is grown now by several techniques in the laboratory and is just a few
nanometers in diameter and several microns long.
CNT
can be metallic or semiconducting and offers
amazing possibilities to create
future
nanoelectronics devices, circuits, and computers.
CNT exhibits extraordinary mechanical properties: the Young's
modulus is over 1
Tera Pascal. It is stiff as diamond. The estimated tensile
strength is 200 Giga Pascal.
These properties are ideal for reinforced
composites, nanoelectromechanical systems
(NEMS).
