Synthesis of Well-Aligned Diamond Nanocylinders

Abstract

Alumina templates are used to assist the deposition of highly ordered polycrystalline diamond nanocylinders (see Figure) and diamond-like carbon nanotubes. The growth of diamond is carried out by microwave plasma-assisted CVD, using acetone as the carbon source. The dimensions of the nanofibers are easily controllable and this technique could be adopted to prepare arrays for various applications.
