In situ fabrication of freestanding single-walled carbon nanotube rope interconnection

A single‐walled carbon nanotube rope interconnect is fabricated by utilizing dielectrophoresis and capillary condensation. The rope connects a pair of prefabricated cantilevers with good alignment and outstanding packing density. The diameter and resistance of the rope are readily controlled by adjusting the dielectrophoresis parameters such as applied voltage and frequency. The properties of the rope, including packing density, electron transport, and maximum current density, are investigated. The maximum current density of the rope is measured to be as high as 1 × 107 A/cm2 in vacuum.
