TLDR
In this paper, the authors show that stabilization of the director field occurs at the chevron interface, so that SC cells behave as two nearly independent cells optically and electrically in series.Abstract:
The recent discovery of ``chevron'' structured smectic-C (SC) layers in surface-stabilized ferroelectric liquid-crystal (SSFLC) cells [T. P. Rieker, N. A. Clark, G. S. Smith, D. S. Parmar, E. B. Sirota, and C. R. Safinya, Phys. Rev. Lett. 59, 2568 (1987)] enables the understanding of many commonly observed features of SSFLC director and layer structure. We present the full three-dimensional layer structure of zigzag walls, the predominant SSFLC defect, which we find to mediate change in chevron direction. We show that stabilization of the director field in SC chevron cells occurs at the chevron interface, so that SC chevron cells behave as two nearly independent cells optically and electrically in series.read more

Director and layer structure of SSFLC cells
TL;DR: X-ray scattering and optical studies reveal two key features of surface stabilized Ferroelectric liquid crystal (SSFLC) cell structure: (1) the temperature dependence of the layer thickness is an important effect in determining both the layer and director-polarization structure; and (2) there exists in some SSFLC cells an internal FLC-FLC interface, where surface stabilization of the director polarization field occurs in addition to that at the FLC substrate interface.
