Claim 0:
1. A method for synthesizing nanotubes of a preselected chirality, the method comprising:
introducing a carbon source into a reactor in the presence of a flowing volume of a catalyst having a diameter corresponding to a diameter of the preselected chirality;
allowing the carbon source to decompose to its atomic constituent to allow attachment of the atomic constituent to the flowing volume of the catalyst for subsequent growth of carbon nanotubes on the flowing volume of the catalyst; and
injecting, into the reactor, an atomic ratio of hydrogen to carbon, where the atomic ratio is greater than, or equal to, about 10/1, subsequent to the attachment of the atomic constituent to the flowing volume of the catalyst to passivate non-armchair growth sites on the carbon nanotubes, so that a volume of carbon nanotubes of the preselected chirality can be synthesized.
