Short presentation
My research is focused on synthesis of materials by magnetron sputtering. I am primarily interested in the physics of reactive sputtering, processes taking place at the surfaces and ion surface interaction especially in HiPIMS. Part of my work is also synthesis of various thin films. These are especially oxides for electronics and optics, and sulfides for photovoltaics.
