Abstract
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. Single walled carbon nanotubes are grown on the fullerene side of the metal layer.
