Nanocrystalline diamond films
Nanocrystalline diamond (NCD) films, have recently attracted considerable interest as they combine (to a large extent) the excellent properties of diamond with very smooth surfaces, which makes them a candidate for many applications such as tribology, optics, microelectromechanical systems (MEMS), biomedicine and biotechnology.
Our current research activities are directed to the deposition of (ultra)nanocrystalline diamond films by microwave plasma chemical vapour deposition and the investigation of their basic (morphology, topography, crystallinity, composition, bonding structure, etc.) (Figs. 1-3) and application relevant (mechanical, optical, electrical, structuring, biocompatibility, bioactivity, etc.) (Figs. 4-7) properties.
