Carbon nanotubes are fabricated using chemical vapor deposition at predetermined locations by patterning catalyst directly on a substrate with nanometer-scale precision using dip-pen nanolithography with multipen cantilevers (see image). The development of new molecular inks for the deposition of the precursor catalyst results in a high yield of isolated carbon nanotubes, ideal for subsequent device fabrication.
