M. Kimura et al., CHARACTERIZATION OF THE ELECTROCLINIC EFFECT OF SMECTIC LCS IN TERMS OF THE TRANSITIONAL DIELECTRIC-CONSTANT IN THE S(A) PHASE, Liquid crystals, 14(6), 1993, pp. 1785-1791
The electric-field dependence of the dielectric constant of some mater
ials which show a strong electroclinic effect in the S(A) phase, has b
een studied by measurement of the transitional dielectric constant. We
suggest that the observed variation of the dielectric constant may or
iginate from the electric field induced dielectric biaxiality; this is
inherent in a material that exhibits the electroclinic effect.
