Magnetic Alignment of Carbon Nanotube Interconnects

Abstract

In recent years, much research effort has focused on advancing the fundamental understanding, growth, and utilization of carbon nanotubes (CNTs). In particular, the precise handling, placement and anchoring of individual nanotubes remain a challenge to realizing practical systems that exploit CNTs' superior electrical and mechanical properties. In this paper, we investigate the use of a novel magnetic alignment technique for establishing CNT interconnections in a 3-D device. Our proposed configuration is compatible with a number of nanoelectronic, subwavelength photonic, and electrochemical energy storage devices and systems.

Exciton Dynamics in Carbon Nanotubes

“…How ever this anisotropy is not obvious in typical as-synthesized samples due to the random orientation of nanotubes. Considerable effort has been m ade to produce structures with aligned nanotubes, by means of m echanical stretching of CNT-polym er com posites [141][142][143][144][145][146], spun com posite fibres [147], application of a m agnetic field [72,148], CVD growth of vertically-aligned SWNTs [149,150], electrical-field assisted thermal annealing [151], and form ation of liquid crystals in certain solvents [152]. These growth m ethods are review ed by lakoubovskii (2009) [153].…”
