"The essence of this project is the implementation of novel low temperature pulsed plasma deposition systems involving magnetron sputtering, hollow cathode method working, surfatron for photoactive hematite (alpha-Fe2O3) thin films production. The prepared films will be characterized by means of many modern methods (e.g. GI-XRD, XPS, UV-VIS, AFM etc.). The photoresponse of the hematite films will be assessed with help of photoelectrochemical experiments. The films\u2019 photofunctionality will be enhanced by targeted modification via particularly their doping, isocrystalline bilayer systems (hematite/Al2O3), and alternatively also by introducing the catalyst nanoparticles isles (IrO2, RuO2) onto their surface. Further, the thoroughly characterized hematite films will be transformed to pyrite (FeS2) by chemical sulfurization. Since pyrite is another potentially very useful photoactive material, suggested to be an inherent part of new generation photovoltaic cells, the correlation between the properties of hematite and pyrite will also be studied (e.g. Hall effect measurements)."@en .
