Light Scattering of Ferroelectric Liquid Crystals Using Rubbing Cell

Abstract

Transient scattering mode (TSM) at the instant of polarity reversal of applied voltage in the chiral smectic C phase of ferroelectric luquid crystals (FLCs) using uniformly aligned cell has been studied. The scattered light in the TSM using uniformly aligned cell has an azimuthal dependence. Polarizing microscope observation of FLC at the instant of polarity reversal of applied voltage has been performed. Parallel stripes have been observed in the microscope figures. The direction of the stripes is tilted to the smectic layer and the tilt direction of the stripes depends on the polarity of applied voltage.
