The inorganic materials are primarily synthetized by state-of-the-art plasma-assisted deposition techniques involving high-power impulse magnetron sputtering (HiPIMS) and plasma enhanced chemical vapor deposition (PECVD) methods as well as chemical pathways such as hydrothermal growth, spray pyrolysis, doctor blading, etc.

  • Pulse modulated (DC and/or RF, MF) reactive magnetron sputtering of nanocrystalline thin films and nanostructures (pure metals, metal alloys, oxides, nitrides, etc.);
  • Experience with the high-power impulse magnetron sputtering (HiPIMS).
  • Utilization of multi magnetron deposition sources (three or more magnetron guns), DC/RF Bias, etc.;
  • Basic and advanced deposition plasma diagnostics (optical emission spectroscopy, Langmuir probes, absorption spectroscopy, etc.);
  • Understanding of advanced methods and results of nanomaterials characterization (HRTEM, TEM, XPS, XRD, Raman spectroscopy, EPR, GI-XRD);

The applicant responsibilities:

  • Controlled deposition of inorganic nanostructured materials (mainly TiO2; α-Fe2O3, WO3, BiVO4, etc.) by aforementioned plasmatic systems.
  • Controlled deposition of thick (up to 10 µm) pure metal (Ti, W, Fe, Zn, Al, etc.) and metal alloys (Ti-Pt, Fe-Ti, Ti-Nb-Ta, etc.) onto various substrates (FTO, glass, metals, etc.) as the starting materials to growth nanostructures by electrochemical anodization;
  • Controlled deposition of multilayers structures, over-coatings of various nanostructures (nanotubes, nanorods, etc.), preparation of gradient heterojunctions, etc.;
  • Deposition plasma diagnostics to correlate the plasma conditions with the films’ physical and functional properties as well as to ensure the process reproducibility
