Research Group Leader
THEMATIC RESEARCH FOCUS
RESEARCH AREAS
- Theoretical studies of electronic and magnetic properties of disordered alloys, epitaxial multilayers, surfaces and interfaces as well as quantum-mechanical studies of extended defects in metallic materials
- Experimental investigations of relations between structure and magnetic, transport and mechanical properties in metallic materials
MAIN OBJECTIVES
Investigation of the functional properties of nanostructures
Specification and optimisation of the functional properties of nanostructures for nanoelectronics, nanophotonics and (bio)sensing, their correlation with geometrical/structural parameters of nanostructures and operational parameters. Novel and unique properties of nanostructures not observable at conventional materials and microstructures open the ways for qualitatively new applications.
CONTENT OF RESEARCH
Investigation of the functional properties of nanostructures
The main goal is to find a correlation between the properties and the geometrical and structural parameters of nanostructures and to use this knowledge for feedback in the technology of their preparation and for various applications.
Magnetic properties and electrical and thermal transport properties of nanostructures, ordered nanostructures, ultrathin layered structures and, high-temperature oxide superconductors will be determined experimentally in the temperature range 1 300 K on a new measuring system which will enable measurements in an external magnetic fi eld up to 9 T. A vibrating sample magnetometer will be used for investigation of magnetic properties at high temperatures. Structural and magnetic properties of Fe based nanostructures will be studied using Mossbauer spectroscopy at low and high temperatures.
