THEMATIC RESEARCH FOCUS
RESEARCH AREAS
- Electronic and vibronic structure of materials and metamaterials
- Optical spectroscopy and polarimetry of micro- and nanostructures
- X-ray analysis of micro- and nanostructures
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 in conventional materials and microstructures which open the ways for qualitatively new applications.
CONTENT OF RESEARCH
Investigation of the functional properties of nanostructures
The main goal is to find the 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.
Self-assembled semiconductor nanostructures, fundamental electronic properties
Self-assembling processes in nanostructures of III-V semiconductors (e.g. self-assembled rings of InAs in the matrix of GaAs). A study of electronic structures aimed at optimising their properties with respect to optoelectronic and transport applications, analysis of the influence of capping layers.
Oxide superconductors and magnetics, transport at optical frequencies
Deposition of layered systems, nanostructures in systems of superconductors/magnetics.
An experimental and theoretical study of electronic and vibrational structures. Optimising them with respect to sensor applications. Experimental determination of the electrical, thermal and magnetic properties of hightemperature superconductors and superlattices with respect to their structural characterisation and chemical composition.
