Abstract
A method is reported for controlling the diameter of single-walled carbon n anotubes (SWCNTs) during the electric-arc-discharge process. Using argon as inert atmosphere provides smaller diameters as compared with those when pu re helium is used. Varying the gas mixture from argon to helium changes the diameter distribution to higher values. A linear fit of the average diamet er shows a 0.2 Angstrom diam decrease per 10% increase in the argon-helium ratio. (C) 2001 American Institute of Physics.
