Computational calculations on chevron structure in ferroelectric liquid crystals
Résumé
In this paper we present numerical results for the chevron structure in a Surface Stabilized Ferroelectric Liquid Crystal (SSFLC)1 sample. Using a phenomenological expression of the Sc bulk free energy and the numerical relaxation method, we calculate the spatial distribution of the director and the tilt of the layer in the chevron for twisted and uniform states for different applied voltages. In particular the results confirm the asymmetrical twist that has been observed in recent experiments.2,3 The calculations take into account specific boundary conditions for both parameters with an applied electric field.
