  Abstract:
Electronic and structural properties of an ultra-small radius single walled carbon nanotube (SWCNT) were studied using density functional linear augmented plane wave (LAPW) method. Different electronic properties of a (4,0) zigzag SWCNT show this ultra-small radius nanotube could not be extracted from the simple folding of a graphene. The calculated value for diameter of the tube is 3.364 ?, in good agreement with experimental results. Density of states and band structure results show the metallic character of (4,0) nanotube. A large van Hove peak near the Fermi energy due to large curvature is a good evidence for charge carriers to show superconductivity in a (4,0) nanotube.
