Abstract

High‐rate cathode growth of nanorods is observed for dc magnetron sputtering of graphite, germanium and molybdenum cathodes despite the sputtering. The growth of vertically aligned carbon nanorods using dc magnetron sputtering with deuterium as the working gas and a polycrystalline nuclear graphite cathode is reported for the first time. Two different types of carbon nanorodes are observed differing in their diameter/length ratio. High‐rate nanorod growth is also observed for the usual magnetron sputtering with argon as a working gas for molybdenum and germanium single‐crystal cathodes. The high growth rate (tens of micrometres per hour) is discussed in the context of ion‐stimulated surface mobility of the neutral atoms and their redeposition in nonhomogeneous cathode sputtering.

In conventional balanced-magnetron (CBM) sputtering, the amount of ion bombardment of the growing film, as measured by the substrate bias current density, is limited to less than 1 mA cm -z. Fast secondary electrons escaping from the target surface quickly find a path to ground and undergo few ioniz
