摘要：

Based upon the Slater-Koster tight-binding calculations, we investigated electronic properties of the "metallic" single-walled carbon nanotubes (SWNTs) in detail. Our results show that tube curvature may produce an energy gap at the Fermi level for zigzag and chiral "metallic" SWNTs, and this effect decreases with the increasing of either the radius or the chiral angle. Our calculated results are in good agreement with experiments.
