Technique to Align Single Carbon Nanotube Growth

Disclosure #: 1076
Description: The global demand for carbon nanotubes is expected to reach $807.3 million by 2011 (Source). One difficulty with carbon nanotube growth is the placement and alignment of individual nanotubes. This new technique utilizes Laser-assisted Chemical Vapor Deposition (LCVD) at relatively low substrate temperatures to align the growth of single-walled carbon nanotubes (SWNT). The key to this current method is the utilization of a laser beam to heat two electrode tip apexes thus creating proper conditions to grow a SWNT connecting the electrodes.
Advantage(s):
  • SWNTs are electrically connected at each end
  • SWNTs can be grown at relatively low substrate temperatures
  • Ability to align the growth of individual SWNTs
Application(s):
  • Microelectronic transistor gates
  • Resonator structures
  • Microelectronic circuit connections
  • Senor devices
  • Field-emission devices
  • Nano-electro-mechanical systems
