Abstract:
1. A method for producing a multiplicity of single walled carbon nanotubes with a narrow diameter distribution from a source of carbon, said method comprising: (a) preparing an arrangement comprising a metal layer, at least one layer of fullerenes in contact with one side of said metal layer, and a solid carbon source in contact with the other side of said metal layer; (b) heating said arrangement to a temperature below where said fullerenes sublime; (c) permitting said at least one layer of fullerenes and said carbon source to dissolve into the metal layer; and (d) growing a multiplicity of single walled carbon nanotubes of a single diameter d, wherein d is within the range of 0.8 to 2.2 nm, at least 80% of said multiplicity of single wall carbon nanotubes having a diameter within ±5% of d.
