Abstract
We report dielectric spectroscopy of a room temperature single phase antiferroelectric liquid crystalline material namely (S)Â +Â (1-methylheptyloxycarbonyl)2-fluorophenyl 4â²-(3-perfluoropropylmethylnoyloxy prop-1-oxy)biphenyl-4-carboxylate in the frequency range 1Â Hz to 35Â MHz under planar anchoring conditions of the molecules. Dielectric, thermodynamic and texture studies confirm a wide room temperature range single antiferroelectric (SmCâa) phase between crystal and isotropic phase of this material. Three relaxation modes (due to collective as well as individual molecular process) appeared in the SmCâa phase. The contribution of ionic conductivity in SmCâa phase has also been determined.
