Expertize

I work in the field of electronic and optoelectronic devices fabrication since 2008 and was member in the research team of more than 16 national and international scientific projects.

I have expertise in:

-       Synthesis of thin films by magnetron sputtering;

-       Characterization of thin film structures: structural (X-ray diffraction, X-ray reflectometry), morphological (atomic force microscope), optical (UV-Vis-IR spectroscopy), and electrical (resistivity/conductivity, Hall effect, dielectric spectroscopy);

-        Fabrication of electronic and optoelectronic devices in clean room conditions and their functional characterization: photovoltaic cells, metal-insulator-metal (MIM) structures, metal-insulator-semiconductor (MIS) structures, and thin film field effect transistors (TFT).

Demonstrated leadership capacities of research project coordination and budget administration; Project leader of:

▪ PN-II-RU-TE-2014-4-1122 „Field effect transistors based on new transparent heterostructures synthesized at low temperatures” project
