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

Abstract

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.

Elastic properties of single-walled carbon nanotube clusters: Dependence on hydrostatic pressure

“…However, to obtain a balanced combination of mechanical and electrical properties of CNTs for some specific applications, it is often desirable to synthesize CNT arrays with a parallel axis to form a cluster of a honeycomb-like structure [2]. These include their applications as springs [3], field emission displays [4], energy storage [5] and electrical interconnection [6]. A CNT cluster has a two dimensional triangular lattice constant, and has a plane of symmetry.…”
