Surface-Induced Flexoelectric Domains in Asymmetrically Strong-Weak Anchored MBBA Films

Abstract

The flexoelectric domains were replaced by electrohydrodynamic instabilities only in the case of strong azimuthal anchoring of the liquid crystal layer.The role of the sign and the value of the dielectric anisotropy, the homogeneity of the electric field as well as the asymmetry in the surface anchoring are discussed in detail.
