Effect of ferroelectric BaTiO(3) particles on the threshold voltage of a smectic A liquid crystal

The influence of small ferroelectric BaTiO(3) particles on the planar–homeotropic transition threshold voltage in smectic A liquid crystals consisting of p-nitrophenyl p-decyloxybenzoate and 4-cyano-4′-pentylbiphenyl were studied by using capacitance–voltage (C–V) measurements. It was shown that the...

description The influence of small ferroelectric BaTiO(3) particles on the planar–homeotropic transition threshold voltage in smectic A liquid crystals consisting of p-nitrophenyl p-decyloxybenzoate and 4-cyano-4′-pentylbiphenyl were studied by using capacitance–voltage (C–V) measurements. It was shown that the BaTiO(3) particles significantly reduce the threshold voltage. The obtained result is explained by two factors: an increase of dielectric anisotropy of the liquid crystals and the formation of a strong electric field near polarized particles of BaTiO(3). It was shown that the role of the second factor is dominant. The explanations of some features observed in the C–V characteristics are given.
