摘要:
A flexoelectric polarization proportional to the splay deformation is expected in phases with local smectic order, because the alternation of highly polarizable molecular cores with paraffinic tails of lower polarizability produces a spatial modulation of electric fields applied normal to the layers, and the locally inhomogeneous field pushes the permanent quadrupole moment of the core along the field direction, coupling with the splay deformations.
