The deformed metal-SWNTs and metal-TCNTs can be transformed to semiconductor or insulator due to deformations resulting to variation of the atomic structure and the nearest-atom transfer integral having relation with the directions.Based on the Boltzmann transport equation and n - electronic energy dispersion relations for individual SWNTs, the theoretical model caculating the current and conductance of the SWNTs is deduced.

我们从Boltzmann方程出发，并结合SWNTs的能量色散关系，导出了计算手性SWNTs电导或电流的理论模型，并分别对非掺杂和掺杂SWNTs的低温电导或电流进行数值计算，结果表明：对于非掺杂的SWNTs，其电导是量子化的，即电导随偏压或电子输运能量变化呈跃变的台阶式结构，这些结构随管径增大或温度升高变得不明显；对于掺杂SWNTs，当偏压为某些特定值V_i时，传导电流有跃变，且传导电流的大小、跃变周期及跃变幅度等不是完全由掺杂后的电子浓度决定的，而与管半径R及掺杂后Fermi能级附近的电子态密度有直接关系，随着温度的升高和管径的增大，跃变结构趋于平滑。
