Abstract
In surface stabilised ferroelectric liquid crystal (SSFLC) cells driven by low voltages, typically below 10V, it is observed that domains of the switched state nucleate and grow, merging to fill the cell. A model of domain nucleation in SSFLCs is proposed, which considers a nucleation site as a local absence of the chevron interface torque. The model is implemented in a two-dimensional simulation of the SSFLC SCE-8 in a chevron configuration with C2 alignment. It is shown to behave realistically over the voltage range 2-10V by comparison with experimental results.
