    摘要: Methods of preparing single walled carbon nanotubes are provided. An arrangement comprising one or more layers of fullerene in contact with one side of a metal layer and a solid carbon source in contact with the other side of metal layer is prepared. The fullerene/metal layer/solid carbon source arrangement is then heated to a temperature below where the fullerenes sublime. Alternatively, a non-solid carbon source may be used in place of a solid carbon source or the metal layer may simply be saturated with carbon atoms. A multiplicity of single walled carbon nanotubes are grown on the fullerene side of the metal layer, wherein at least 80% of the single walled carbon nanotubes in said multiplicity have a diameter within ±5% of a single walled carbon nanotube diameter D present in said multiplicity, said diameter D being in the range between 0.6-2.2 nm.
