Coiled carbon nanotubes: their structural and electrical properties

Coiled carbon nanotubes exhibit excellent mechanical and electrical properties because of the combination of coil morphology and properties of nanotubes. They could have potential novel applications in nano-composite, nano-electronic devices as well as nano-electromechanical system (NEMS). In this work, synthesis of regularly coiled carbon nanotubes is presented. It involves pyrolysis of hydrocarbon gas over metal/support catalyst by conventional thermal filament CCVD and microwave CCVD methods. The growth mechanism and structural and electrical properties of coiled carbon nanotubes are also discussed.
