Antiferroelectric dielectric relaxation processes and the interlayer interaction in antiferroelectric liquid crystals
Antiphase relaxation process of antiferroelectric phase is investigated in binary mixtures of antiferroelectric and ferroelectric liquid crystalline compounds. It is found that the frequency of the antiphase mode ranges from 2 to 4 MHz, being one of the fastest collective processes reported so far. This can be exploited in a photonic switch with a submicrosecond response time. However, the freq...
متن کاملProperties 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...
متن کاملAntiferroelectric liquid crystals
2014 Dielectric investigations have been undertaken in two thermotropic liquid crystal systems exhibiting a smectic A2 phase (i.e. with the layer spacing equal to twice the molecular length). The postulated antiferroelectric ordering has been supported by these measurements. There are anomalies in the dielectric constants 03B5~ and 03B5~ at the N-SA2 transition and an unusual low frequency rela...
