Nano- and ultrananocrystalline diamond (NCD and UNCD) films, have attracted in the last decades considerable interest as they inherit (to a large extent) the excellent properties of diamond combined with smooth surfaces and possibilities to coat substrates of different materials, sizes and shapes. This makes them candidates for applications in various fields such as tribology, optics, microelectromechanical systems (MEMS), quantum information technology, biomedicine, biotechnology and many others.
Our current research activities are directed towards deposition of UNCD and NCD films by microwave plasma or hot-filament chemical vapour deposition (MWPCVD and HFCVD) and the investigation of their basic (morphology, topography, crystallinity, composition, bonding structure, etc.) and application relevant (mechanical, optical, electrical, biocompatibility, bioactivity, etc.) properties. We study also the surface modifications of NCD and UNCD by plasma and photochemical processes and different following functionalizations as well as the fabrication of diamond nanostructures applying lithography and dry etching.
All these activities are supported by diverse projects as summarized below.
