Objective
- To understand the switching behaviour in ferroelectric liquid crystals compared to ferroelectric liquid crystalline polymers;
- Determination of the physical parameters (i.e. spontaneous polarisation, rotational viscosity's, tilt angle) of the FLC's under investigation;
- To understand the influence of high spontaneous polarisation and dislocation domain formation on the structural parameters of ferroelectric liquid crystals;
- The tilt angle measurements by X-ray and optical methods should be compared, the dielectric data must be evaluated;
- To study thin and ultrathin smectic C* films by X-ray reflectivity.
- The objectives to the five points in question could be answered with detailed, specific results.
Follow up
Both groups are continuously co-operating by :
- Dielectric relaxation spectroscopy on low molar mass and polymeric FLC's;
- Pyroelectric investigations on FLC's;
- Development of devices for application as spatial light modulators based on FLC's;
- Using both capabilities in solving questions related to EPR and magnetic properties of exchange coupled systems.
- Analysing the fast switching behaviour (S) in low molar mass FLC's and the switching properties (mS) in side chain polymers by triangular wave methods;
- Determination of the spontaneous polarisation with different techniques (Hysteresis method and reversal current method), tilt angle (X-ray and electrooptic technique, and rotational viscosity's from dielectric and electroptic measurements;
- Mixtures of FLC's showing up different values of spontaneous polarisation were investigated by polarising microscopy light diffraction and dielectric spectroscopy. A relation between the value of the spontaneous polarisation and the domain periodicity was established;
- The zigzag defects and the microdomains in surface stabilised liquid crystal cells were carefully analysed by means of light scattering method. The tilt angle as function of temperature obtained by different techniques was analysed. The dielectric relaxation spectroscopy in a broad frequency region allowed to detect molecular and collective relaxation processes;
- X-ray reflections on ultrathin film allowed to study the layer thickness properties and interfaces properties.
