Electrooptic Effect in Homeotropically Aligned Ferroelectric Liquid Crystal

Abstract

Abstracl. The current-voltage characteristics of high-quality YBCO thin films deposited onto MgO have been measured in both zero and finite applied magnetic fields. The wide dynamic range of the measurements, the high experimental precision and the observation of extremely well defined power law behaviour below the phase transition temperature have enabled u s to demonstrate that vortex glass scaling does not occur, and that 2D vortex unbinding provides a better account of the results.

Electro-optic switching in spin-coated ferroelectric mesomorphic polymer films and its analysis

“…In Ref. 6, a conventional sandwich cell filled with low-molar mass smectic C* liquid crystal was used to record the switching characteristics in the cell in which smectic layers are parallel to the substrate.…”

Field Induced Helix Anharmonicity and Fast In-Plane Electrooptic Switching of Chiral Liquid Crystals

“…This should be taken into account when the experimental data are compared with calculations assuming the uniform in-plane field everywhere. The cell is placed between two polarizers (6). The bipolar, rectangular, voltage pulses of varied frequency, duration and duty time were synthesized using voltage generator G5-30A (Russia).…”

“…Later Soref [5] studied IPS-regime with different boundary conditions (planar, homeotropic, etc.). Then similar investigations were carried out on ferroelectric liquid crystals [6,7]. To date the electrooptic effects based on the orientational phenomena in nematics are well understood and find applications to technology for improving angular characteristics of displays [8,9].…”

Fabrication of vertical alignment in ferroelectric liquid crystals for display application

“…12,[16][17][18][19][20][21][22][23][24][25][26][27][28] The large optical leakage and low contrast ratio due to the nonuniformity and defect of FLC molecular alignment are examples of the main problems of the application of FLCs to the display devices. In this study, therefore, we focus on vertical alignment FLCs (VA-FLCs) [29][30][31][32][33] fabricated without the rubbing technique. A high contrast ratio is expected, and the fabrication process can be simplified because it does not require the rubbing technique.…”
