摘要：
The authors use the density functional theory associated with nonequilibrium Green function to calculate (2,2) and (3,3) single-walled nanotubes. The result of T(E) imply that pi or pi(*) band has been suppressed at certain electronic energy region result in the effect of curvature induce complex hybridization procedure. In view of the I-V characteristics of (2,2) tube, it is found that the current curve appears to have an oscillation behavior. These peculiar electronic transport properties of small diameter tube directly relate to a large curvature effect, which may be useful for the manufacture of electronic applications.
