New Electrooptic Switching in Ferroelectric Liquid Crystal Cells

Abstract

The magnetization recovery of a two-dimensional ferromagnetic system after excitation by intensive ultrafast pump pulses is investigated by a Monte Carlo method with a focus on the evolution of domain structure and the magnetization in the equilibrium state. Our simulations can explain the effect of the pumping fluence on the recovery process. In particular, they reveal the importance of domain formation in the recently reported accumulation effect already found by the pump-probe magnetization hysteresis loop measurement of a metallic ferromagnetic film. In the framework of the model, it is predicted that by repeating pump pulses a sufficient number of times, the magnetization of the two-dimensional ferromagnetic system can be eliminated when the pump fluence is above a critical value. #

Ferroelectric liquid crystals: Excellent tool for modern displays and photonics

“…The relationships (12) and (13) were confirmed experimentally in Beresnev et al . Similar effect for the FLC material pitch ~0.6 µm has also been reported by Ouchi et al . Using a “natural” gray scale of the DHF mode, many gray levels have been obtained with fast switching between them .…”

Optics and electrooptics of chiral smectic C liquid crystals

“…В заключение отметим, что в некоторых работах, появившихся в последнее время, отмечен ряд новых особенностей электрооптических свойств С*ЖК, ко торые не укладываются в упомянутые выше пред ставления: это, например, появление третьего ста бильного состояния в поверхностно стабилизиро ванных структурах, обладающих высокой спонтан ной поляризацией (~ 100 НК/см ) [126], переклю чение, связанное с движением дисклинаций между твистовыми состояниями [127] и т.д.…”

P‐113: Ferroelectric LC Aligned on SiO2 Thin Films Using the Ion Beam Deposition and its Applications

“…Application of obliquely evaporated SiOx thin films for FLC aligning has already been investigated in late 1980s [3][4]. As high FLC pretilt angles on the surface are induced in this method, the zig-zag defects could be eliminated [4].…”
