Research Group Under
the Supervision of Prof. A. S. Opanasiuk
The research group is engaged in studying the structural, electrical, and optical properties of films of new semiconductor materials for flexible and transparent electronics—compounds like CdTe, CdSe, ZnTe, ZnSe, ZnS, ZnO, CuO, Cu2O, NiO, Zn2SnO4, CdMnTe, CdMnS, SnS, SnS2, SnSe, Cu2ZnSn(SxSe1-x)4, Cu2MgxZn1-xSnS4. The scientists are analyzing defect formation processes in the obtained materials, as well as investigating the properties of thin-film heterojunctions based on these compounds. The group is creating device structures (solar cells, radiation detectors, gas detectors) based on heterojunctions and semiconductor-metal structures for electronics, sensors, and solar energy applications.
