Electro-optic and dielectric investigations of a perfluorinated compound showing orthoconic antiferroelectric liquid crystal

Abstract

We observed microsecond order response ranging from 100 to 600μs with respect to temperature for a single component fluorinated rigid core antiferroelectric liquid crystals having highly tilted phases. In the antiferroelectric region, we observed V-shaped electro-optic switching in a 4μm indium tin oxide coated homogeneously aligned cell having PS, ranging from 100 to 200nC/cm2. Dielectric studies have revealed an interesting phase that exists during heating in the temperature region between 74°C and 84°C. From dielectric results studied we calculated activation energies associated with different relaxation modes using Arrhenius law.
