Dynamic scattering applications

Thermotropic cholesterics have several practical applications, some of which are very widespread. Most of the liquid crystal displays produced use either the twisted nematic (see Figure 7.3) or the supertwisted nematic electrooptical effects.6 The liquid crystal materials used in these cells contain a chiral component (effectively a cholesteric phase) which determines the twisting direction. Cholesteric LCs can also be used for storage displays utilizing the dynamic scattering mode.7 Short-pitch cholesterics with temperature-dependent selective reflection in the visible region show different colors at different temperatures and are used for popular digital thermometers.8...

The most important question for the calculation of the structure amplitudes from the intensities is that for the validity of the kinematical approximation. Due to the strong interaction of fast electrons with matter the effects of dynamical scattering become more pronounced with increasing size of the microcrystallites in the film. In order to justify application of the kinematical equations it is necessary that the diffracted intensity is much less...

LEED does not only reveal the relative periodicities of the adsorbate mesh with respect to the substrate lattice. Applying dynamical scattering theory, i.e., modeling the scattering intensity of diffracted beams versus electron energy (so-called I-V curves), allows determination of absolute positions of atoms on the surface [20]. Unfortunately, the complexity of the method limits the number of atoms per unit cell and makes it applicable only to atomic or small-molecule lattices.

The application of a high-frequency electric field to the electrodes induces a transition from the turbid focal-conic texture to the transparent planar texture. This effect is used to erase the light-scattering state obtained after the application of a constant or low-frequency electric field to the cell in the dynamic scattering storage effect described in Section 6.3.
