Investigation of intermetallics and semiconductors and possible application in renewable energy sources

Using numerous experimental techniques in combination with theoretical modeling, we will continue to investigate the spectroscopic, structural, micro-dynamic and sorption characteristics of functional materials: intermetallic phases of transition metals and rare earths, impurities in semiconductor and metallic matrices, nanocomposites and superalloys. Our research will be based on the following experimental methods: time differential perturbed angular correlation, ?össbauer spectroscopy, X-ray absorption fine structure spectroscopy, investigation of hydrogen absorption/desorption process in materials, as well as electrolytic hydrogen production using specific cathode materials. A significant support to our experimental research will be provided by theoretical first principle calculations, based on the density functional theory, of a number of physical properties of the investigated materials. Combining the experimental and theoretical results and analysing them on a nanometer scale, we will be able to find out more about the local and electronic structures, hyperfine interactions and lattice relaxation around the incorporated impurities. These investigations will enable prediction of more efficient functional materials with a wide range of applications, including their potential use as renewable energy sources. The quality of our research will be improved through the established long-term collaborations with our foreign research partner institutions and individuals.
