Terminal–Terminal Types of Liquid Crystals. I. Synthesis and Electrooptical Properties of a Ferroelectric Liquid Crystal

Properties and Applications of Ferroelectric Liquid Crystals

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 stro...

Ferroelectric liquid crystals

2014 A general symmetry argument is presented, and experiments on newly synthesized p-decyloxybenzylidene p’-amino 2-methyl butyl cinnamate are described, demonstrating that chiral smectic C and H liquid crystals are ferroelectric. Some of the properties of this new class of ferroelectrics are discussed. In spite of speculation on the possibility of ferroelectric liquid crystalline phases [1], ...

Ferroelectric volume effect and surface induced fast instabilities for rapid electrooptical displays in liquid crystals

2014 One system exist which is capable of microsecond electrooptical switching in liquid crystals, on polarized light. It is the well-known SC* valve, which uses a volume smectic ferroelectric material and a weak surface anchoring. A new effect is presented which gives rise to localized polar surface instabilities. Some of these surface induced instabilities persist for high frequency (1 MHz) A...
