The invention provides a process for production of carbon nanotubes
whereby a laminate prepared by alternating lamination of a metal catalyst
and a material other than the metal catalyst is cut to expose the
laminated structure, and carbon nanotubes are grown on the metal catalyst
at the cut surface of the laminate. The process results in high-quality
carbon nanotubes, with minimized bundle growth, which are each
individually and independently arranged in a highly precise manner at
prescribed locations.The invention also provides a carbon nanotube
production process comprising a step of preparing a substrate which is
inclined in one or two dimensions from a specific highly symmetrical
crystal orientation and vapor depositing a metal catalyst along the
atomic steps appearing on the surface of the substrate, and a step of
growing the carbon nanotubes by chemical vapor deposition (CVD) using the
metal catalyst as nuclei. It is thus possible to control the growth
locations, diameters, orientation and chirality of carbon nanotubes.
