Materials for Nanosystems and Biointerfaces Research Group

The Materials for Nanosystems and Biointerfaces (MNB) research group studies the preparation and the properties of diamond. Diamond layers are fabricated by plasma enhanced chemical vapour deposited (CVD) method using commercial and homemade reactors. These layers are prepared in pure form or doped (e.g. Boron, Phosphorous and Nitrogen) for quantum optic, electrochemical or electronic applications with different crystalline forms, i.e., form nanocrystalline diamond (NCD) layers and to monocrystalline or epitaxial diamonds (SCD) layers. Diamond properties and diamond-based prototype applications are studied within the MNB group or the Institute of Physics CAS facilities and in cooperation with other national and international institutions.
