Properties and Applications of Ferroelectric Liquid Crystals
نویسنده
چکیده
The ferroelectric modes of liquid crystals which allow for easy reorientation of the direction of polarization make liquid crystals an attractive element to use for applications such as optical storage, and optical switching. Three schemes for achieving ferroelectricity are discussed: chiral smectic alignment, achiral “banana-shaped” smectic alignment, and the nematic phase that comes from strong dipole interactions. We also examine how ferroelectric liquid crystals can be used for thresholdless switching and optical storage.

متن کاملFreedericksz transition threshold in nematic liquid crystals filled with ferroelectric nano- particles
A key liquid crystalline property for electro-optic applications is the Frederiks threshold electric field. There has been recent experimental interest in liquid crystal-based colloidal suspensions in which the colloidal nanoparticles both possess a permanent electric polarization and provide strong director anchoring on the particle surface. Such suspensions are sometimes known as Filled Liqui...
متن کاملTheory of ferroelectric nanoparticles in nematic liquid crystals.
Recent experiments have reported that ferroelectric nanoparticles have drastic effects on nematic liquid crystals-increasing the isotropic-nematic transition temperature by about 5 K, and greatly increasing the sensitivity to applied electric fields. To understand these effects, we develop a theory for the statistical mechanics of ferroelectric nanoparticles in liquid crystals. This theory pred...

A diffraction modulator that exploits the transverse electro-optic effect in ferroelectric liquid crystals is proposed for applications in displays and in spatial light modulators. Experiments with a short-pitch ferroelectric liquid crystal aligned homeotropically show an achromatic contrast ratio of greater than 100:1 available with oblique readout. The sources of the contrast deterioration an...
متن کاملEmerging Applications of Ferroelectric Nanoparticles in Materials Technologies, Biology and Medicine
Consider an insulating system with non-zero spontaneous polarization Ps (dielectric di‐ pole moment per unit volume). If an applied external electric field E that is greater than the so-called coercive field Ec can reverse Ps then our system is a ferroelectric system. Ferroelectricity has a long and exciting history described in [1,2]. In the beginning of its historical development (the Rochell...
