Research topics

The research area includes conceptual analysis and experimental research, focused on obtaining new materials with desired properties, with particular focus on the perspective of their technological applications. The main goal of the development of advanced materials is to increase the comfort and quality of life of people, solve the biggest civilization problems related to the deficit of energy, water, food and climate change and limit the negative effects of technological development. The creation of advanced materials requires knowledge about the crystal and electronic structure and improving the ability to manipulate matter (also at the atomic scale). The efficiency and repeatability of research conducted in recent years have significantly increased, which is directly related to the progress in the field of scientific instruments and their software. The university has a group of modern and comprehensively equipped laboratories, dedicated both to the production and characterization of manufactured materials, as well as experienced staff.

The Laboratory of Electron Spectroscopies and Functional Materials ESpeFuM conducts research on materials and material structures for applications in electronics, photovoltaics and metrology, including interfaces and the surfaces of inorganic-organic hybrid structures. It offers measurements using spectroscopic methods: ultraviolet and X-ray photoelectron spectroscopies (UPS, XPS), Auger electron spectroscopy (AES) photoemission yield spectroscopy (PYS), thermo-programmed desorption (TDS), impedance spectroscopy (IS). Complementary measuring methods are scanning microscopies: scanning electron microscopy (SEM), atomic force microscopy (AFM), electric force microscopy (EFM), scanning thermal microscopy (SThM) and Kelvin probe microscopies (SKPM). Moreover, a wide range of optical and photoelectric methods are available (photoluminescence, photoconductivity, surface photovoltage, photo capacity) as well as thermal measurements including photothermal techniques and differential scanning calorimetry (DSC). The laboratory is also equipped with an ultra-high-vacuum technological setup for manufacturing of thin-film hybrid structures by physical vapour deposition (PVD) with the ability of in-situ transfer to ultra-high-vacuum research chambers.

Here, at SUT, we tackle their key challenges to open the route towards their implementation in real life for the benefit of society. To reach this goal, we have developed a range of innovative methods of synthesis and assembly into macroscopic networks (fibres, coatings, etc.). Moreover, we have designed highly precise methods of control of their structure to tailor the properties of the obtained material for the selected applications. These novel materials are envisioned to play a key role in photonics, electronics and many other fields of exploitation. The Silesian University of Technology Researchers is experienced in the synthesis of advanced organic materials including conjugated polymers, physicochemical and electrochemical characteristics of polymers, oligomers, composites and small molecules. The scope of research and development is in the field of synthesis and characterization of new organic materials for optoelectronics, photovoltaics and electrochromic materials and the formation and analysis of organic electronic devices. SUT scientists have developed new exciplex emitters and thermally activated delayed fluorescence for use in OLED displays and lighting and together with the funding from the European Union and the Horizon 2020 program were able to cooperate with renowned research institutions and companies in this field. Organic Electronics is currently at the top of scientific interest and many companies are investing in the development in this area (Apple, LG, Samsung). In Poland, the Silesian University of Technology is the only institution operating on wider aspects of organic electronics and cooperating with many international companies like AIXTRON S.E., KGgA Merck, Novaled (Samsung), Cynora, Pratt and Whitney Canada.
