摘要：
By introducing the sp(3)s* Light-binding model, the band structure and electronic density of states of single-walled carbon nanotubes are calculated. It is found that "metallic" zigzag single-walled carbon nanotubes open gaps about 7 meV-0.2 eV near Fermi level. In addition, the changes of diameter and chiral angles plays important roles in electronic properties of carbon nanotubes, especially of small-diameters tubes.
