Submicron patterning of Co colloid catalyst for growth of vertically aligned carbon nanotubes

A highly purified and concentrated monodisperse cobalt colloid was produced to use as a catalyst for growth of carbon nanotubes. Nanocontact printing was employed to deposit the cobalt nanoparticles in regular patterns with feature sizes down to 100 nm onto silicon wafers at low cost over large areas.

Vertically aligned carbon nanotubes were selectively grown by direct current plasma enhanced chemical vapour deposition at temperatures ranging from 300 °C to 550 °C.
