Abstract

Highly ordered oxide nanotubes are fabricated by a simple two-step method which consists of the magnetron sputtering deposition of copper nanowires on nanograted template surfaces and the thermal oxidation of the nanowires in ambient air at 300 °C. The formation of the organized copper oxide nanotubes is explained according to the nanoscale Kirkendall effect which comes into play at the metal/metal-oxide interface during the annealing process.
