Study of relaxation process on ferroelectric/antiferroelectric liquid crystal mixture after electric field-induced phase transition

Abstract

Dielectric measurements were carried out to clarify the behavior of the liquid crystal(LC) phase with V-shaped response that appears in a mixture of a ferroelectric LC and an antiferroelectric LC.　The ground state of the phase is the antiferroelectric phase with four layers. Once it turns to the ferroelectric phase by applying an electric field, it shows ferroelectric behavior for a long time. In this study, we investigated the relaxation process from the ferroelectric state to the ground state by dielectric measurements under a weak applied electric field.
