Electric-Field Induced Tricritical Points in Antiferroelectric Liquid Crystal

Andika Fajar

Abstract


The electric field effect on the smectic-A - smectic-C* phase transition of antiferroelectric liquid crystal have been investigated theoretically. A phenomenological theory under DC field has been developed to establish the calculated hysteresis loop and the E (electric field)−T (temperature)phase diagram, in which a tricritical point was found.

Keywords


phase diagram; tricritical point; antiferroelectric liquid crystal; Landau theory
