چکیده
Surface electroclinic effect in chiral nematic IN") phase of high-tilt-angle ferroelectric liquid crystal has been studied by dielectric relaxation and electro-optical method in a homogeneously aligned, thin samples in the frequency range of 400 Hz to loo kHz at different temperatures. The electroclinic effect in the N* phase observed in the surface layers is due to the effect of surface anchoring and smectic-like ordering of the molecules at the rubbed boundary surface of the sample which has been confirmed by dielectric and optical observations.

Electroclinic effect and modulated phases in smectic liquid crystals.
We explore the possibility that the unusually large electroclinic effect observed in the smectic-A phase of a ferroelectric liquid crystal arises from the presence of an ordered array of disclination lines and walls in a smectic-C* phase. If the spacing of these defects is in the subvisible range, this modulated smectic-C* phase would be similar macroscopically to a smectic-A phase. The applica...
متن کاملFerroelectric ordering and electroclinic effect in chiral smectic liquid crystals.
Ferroelectric ordering, the electroclinic effect, and chiral smectic C(SmC*)-smectic A phase transitions in thin planar ferroelectric liquid crystal (FLC) cells are studied by means of linear electro-optic and second harmonic generation (SHG) techniques. The ferroelectric switching is detected in biased FLC cells by measuring azimuthal dependences of linear and nonlinear responses. The applied ...
متن کاملFast switching characteristics of a microlens array using the electroclinic effect of SmA* liquid crystals.
We present a microlens array characterized by the electroclinic effect of chiral smectic A (SmA(*)) liquid crystals, which show the very fast dynamic switching characteristics required in high-speed optical devices. In order to easily control the intensity at the focal length of the proposed dynamic microlens structure, we adopt a solid-type liquid crystal polymer with optical anisotropy, which...
متن کاملQuasidivergent nematic surface electroclinic effect.
A polyimide coated substrate is treated so that vertical liquid crystal alignment (theta=0) obtains over the temperature range T(NA)< T < T(a), where T(NA) is the nematic-smectic-A transition temperature. When the cell is filled with a chiral liquid crystal whose helical pitch is unwound (surface stabilized), application of an in-plane electric field for T(NA)< T < T(a) induces a nonzero polar ...
متن کاملElectroclinic effect in a chiral carbosilane-terminated 5-phenylpyrimidine liquid crystal with 'de Vries-like' properties.
The chiral carbosilane-terminated liquid crystal 2-[(2S,3S)-2,3-difluorohexyloxy]-5-[4-(12,12,14,14,16,16-hexamethyl-12,14,16-trisilaheptadecyloxy)phenyl]pyrimidine () undergoes a smectic A*-smectic C* phase transition with a maximum layer contraction of only 0.2%. It exhibits an electroclinic effect (ECE) comparable to that reported for the 'de Vries-like' liquid crystal and shows no appreciab...
