Electrically driven gallium movement in carbon nanotubes is discussed. A higher current (15 mA) makes the gallium migrate sharply toward the anode, which increases its mass transport speed with time in the range of 0 to more than 10.345 fg s(-1). In contrast, a lower current (2 mA) only drives gallium to contact the anode, which decreases the resistance of the nanocomposite sharply, from 2.564 kΩ to 0.4 Ω. These results are valuable for designing electrically driven nanomass delivery and nanoswitches, respectively.
讨论了在碳纳米管中电驱动镓的运动。较高的电流（约 15 mA）使镓急剧向阳极迁移，从而使其在 0 到超过 10.345 fg s(-1) 的范围内随时间推移的质量传输速度加快。相比之下，较低的电流（约 2 mA）仅驱动镓接触阳极，从而使纳米复合材料的电阻急剧从 2.564 kΩ降低至 0.4 Ω。这些结果对于设计电驱动纳米质量输送和纳米开关分别是有价值的。
