通过将单壁纳米管浸入液态汞中，研究了提纯对单壁纳米管室温电子输运性能的影响。提纯后的单壁碳纳米管的电导曲线呈平台状，表明其电阻与连接电极的管子长度之间的关系很弱，这为单壁碳纳米管的准弹道导电提供了证据。提纯后的单壁碳纳米管的电子平均自由程达到了几个微米，比原生单壁碳纳米管的电子平均自由程要长，这与基于声学声子散射的计算结果一致。
The effect of purification on room temperature electronic transport properties of single-wall nanotubes (SWNT) was studied by submerging the nanotubes into liquid mercury. The conductance plots of purified SWNTs showed plateaus, indicating weak dependence of the electrical resistance on the length of the tube connecting the electrodes, providing evidence of quasiballistic conduction in SWNTs. The electronic mean free path of the purified SWNTs reached a few microns, which is longer than that of the as-produced SWNTs, and which is consistent with the calculation based on the scattering by acoustic phonons.
