• CNT (Carbon Nanotube) Description:

  CNTs (carbon nanotubes) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 28,000,000:1, which is significantly larger than any other material. These cylindrical carbon molecules have novel properties that make them potentially useful in many applications in nanotechnology, electronics, optics and other fields of materials science, as well as potential uses in architectural fields. They exhibit extraordinary strength and unique electrical properties, and are efficient thermal conductors. Their final usage, however, may be limited by their potential toxicity and controlling their property changes in response to chemical treatment.

a) Electrical conductivity -- probably the best conductor of electricity on a nanoscale level that can ever be possible.

b) Thermal conductivity -- comparable to diamond along the tube axis.

c) Mechanical -- probably the stiffest, strongest, and toughest fiber that can ever exist.

d) Chemistry of carbon -- can be reacted and manipulated with the richness and flexibility of other carbon molecules. Carbon is the basis of most materials we use every day.

e) Molecular perfection -- essentially free of defects.

f) Self-assembly -- strong van der Waals attraction leads to spontaneous roping of many nanotubes. Important in certain applications.

• CNT (Carbon Nanotube) Potential Market Applications:

  Summary Statement: "The primary potential advantages for carbon nanotubes are their very high carrier mobility28, and ultra-thin body but very difficult challenges must be overcome for them to be practical. Key challenges for carbon nanotubes to be viable in high performance FETs is the requirement for processes that provide a tight distribution of semiconductor bandgaps, with each nanotube placed in a desired location, with a specified direction, high adhesion to gate dielectric, low contact resistance, and catalyst compatible with CMOS."
