Claim 11:
12. A method for synthesizing zigzag 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 the zigzag 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 less than about 10/1, subsequent to the attachment of the atomic constituent to the flowing volume of the catalyst so as to minimize the formation of extraneous carbonaceous material while still allowing growth sites on the zigzag nanotubes to remain active, so that a volume of the zigzag nanotubes of the preselected chirality can be synthesized.
