Formation characteristics of horizontal chevron structures in ferroelectric liquid crystal cells

The formation process of field induced smectic C* layer structures known as 'horizontal chevrons' has been investigated as a function of external parameters. Characteristic dimensions of field induced domains, as well as the dynamics of their formation process are reported for a variation of cell gap, applied electric field amplitude, frequency and temperature. The experimental data are discussed in terms of liquid crystal-surface interactions, director switching and effects of ionic motion.
