Nanostructured and organic semiconductors form the basis of a new generation of prospective materials for solar cell fabrication. The efficiency of solar cells crucially depends on the speed of long-range charge carrier transport and the understanding of the transport mechanisms in the mentioned materials is a key knowleged for its improvements....
Metamaterials are artificially created composite periodic structures with a unit cell much smaller than the targeted wavelength of the radiation. These materials may exhibit electromagnetic properties not found in nature. It appear that by using a suitable combination of composite constituents it is possible to conceive for example an “...
We investigate materials with globally or locally broken center of inversion, such as piezoelectric, ferroelectric, antiferroelectric, relaxor or incommensurate dielectrics in form of crystals, ceramics, films as well as complex nanostructures. The team focuses on developing preparation methods, by characterization of structural phase transitions...
We focus on study of dielectric spectra of ferroelectrics in the form of single crystals, ceramics, thin films and multilayers in a very broad spectral and temperature range (1 mHz – 150 THz, 5 – 950 K).
Investigations of novel liquid crystals with dipolar order, understanding of their phase diagram, topological defects and low frequency relaxations responsible for dielectric behavior.
Terahertz (THz) radiation lies in the frequency range between the infrared and microwaves, i.e. between 100 GHz and 10 THz. These waves are able to excite soft polar phonons in solids, vibrations of larger chains in biomolecules, to induce plasma oscillations of free charge carriers with concentrations of ~1014–1018 cm-3 and to interact with...
