This invention relates generally to forming a patterned array of
single-wall carbon nanotubes (SWNT). In one embodiment, a nanoscale array
of microwells is provided on a substrate; a metal catalyst is deposited
in each microwells; and a stream of hydrocarbon or CO feedstock gas is
directed at the substrate under conditions that effect growth of
single-wall carbon nanotubes from each microwell.
