Carbon Nanotubes As Quantum Wires
The carbon nanotube is an example of a quantum wire. A metallic single-walled carbon nanotube that is sufficiently short to exhibit no internal scattering (ballistic transport) has a conductance that approaches two times the conductance quantum, . The factor of two arises because carbon nanotubes have two spatial channels.

Famous quotes containing the words quantum and/or wires:
“A personality is an indefinite quantum of traits which is subject to constant flux, change, and growth from the birth of the individual in the world to his death. A character, on the other hand, is a fixed and definite quantum of traits which, though it may be interpreted with slight differences from age to age and actor to actor, is nevertheless in its essentials forever fixed.”
—Hubert C. Heffner (1901–1985)
“Putting people in a room and strapping wires to their wrist to find out if I make them tingle when I’m telling them about Beirut is a long way from Edward R. Murrow.”
—Linda Ellerbee (b. 1932)
