摘　　要：The electronic localization lengthsλof metallic carbon nanotubes with different chiral symmetries have been calculated by one parameter scaling method.It is found thatλis independent of the nanotube chirality,but depends linearly on their diameters.The dependence ofλon the disorder strength W has also been studied,and a power-law relation betweenλand W is also found to be independent of the tube chirality.Our numerical results are in good agreement with recent experimental observations and other theoretical result for only the“armchair”nanotubes.
