carbon nanotubes

known as CNT is actually a carbon molecule. they are very thin and can be used for many applications. They are synthesized by many methods. Important methods are pyrolysis method and arc discharge method. it assumes three forms namely armchair, zigzag and chiral. They are mechanically strong, highly elastic, possess high thermal conductivity, very stable, metallic or semiconducting depending upon size and have high current carrying capacity.
