The main research task of our team is the growth of low dimensional structures: nanowires, quantum dots, quantum wells composed of II-VI semiconductors and their structural and chemical characterization including optical properties of individual nano-objects. Recently, our research interest is broadened by fabrication and optical properties of two-dimensional (2D) materials: indium selenide, molybdenum diselenide, antimony triselenide.
The basic method for the fabrication of nanostructures is the molecular beam epitaxy (MBE). Our team disposes of two MBE setups coupled under high vacuum: EPI 620 equipped with Te, Cd, Zn, Mn, Mg, I effusion cells and nitrogen RF plasma source and PREVAC equipped with Se, Zn, Cd, Pb, Sb, In effusion cells and electron gun for the deposition of Mo, Co and Au.
