Effect of a surfactant on the electro-optic response in ferroelectric liquid crystals
Vorflusev V. P. , Kosygina M. A. , Chigrinov V. G.
The interaction of mobile surfactant ions in the alignment layer and the surface charges produced by the spontaneous polarization of a ferroelectric liquid crystal (FLC) leads to the appearance of a monostable response of the FLC. The source of the monostability is the internal field produced in the FLC by the surfactant ions in the alignment layer.
