• ferroelectric BaTiO3 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 BaTiO3 particles significantly

• threshold voltage was related to the modification of dielectric anisotropy of LC and the calculated decrease of the threshold was also insignificant. The strong decrease in the threshold voltage by adding of ferroelectric BaTiO3 particles can be explained by the appearance of a strong local electric field
