Abstract

The fabrication of ordered arrays of oriented and bent carbon nanotube on a patterned silicon surface with a micron scale spacing extending over millimeter size surface areas, was presented. A combination of multistep purification and oxidation procedures were used to generate bundles containing 3-20 nanotubes of high purity. The patterned surface was composed of alternating hydrophilic and hydrophobic stripes. The results suggest that the patterning is controlled by the hydrodynamic behavior of a fluid front and orientation and bending mechanisms are facilitated by the pinned carbon nanotubes trapped by the liquid-solid-vapor contact line. / open / 84 / 92
