Dielectric response of ferroelectric liquid crystals in samples of finite thickness

Popis výsledku v původním jazyce

The structure in real planar samples of ferroelectric liquid crystals as well as the collective modes characterizing these structures, are strongly affected by surface anchoring of molecules. This is reflected in dielectric properties, which become significantly dependent on the sample thickness. The dielectric strength and the relaxation frequency of the characteristic modes (pinned Goldstone mode for thick samples and twisted mode for thin ones) are determined and found that for both types of structures dielectric strength increases and relaxation frequency decreases with increasing sample thickness. We proved theoretically predicted thickness dependences of various physical parameters for new FLC compound. We concluded the experimental results are in accordance with the theory taking into account the real structure of samples.n
