Further Experimental Evidence for the Wall Structure of the Flexoelectric Domains in Symmetrically Weakly-Anchored MBBA Layers

摘要: Abstract An attempt for measuring of the penetration non-critical length MBBA flexoelectric surface-induced domains is made. The disappearance into subcritical regions related to strong nonhomogeneity electric field around gap which able inhibit domain formation. electrohydrodynamic generated from ones, on other hand, shows their secondary character as well. existence further confirmed with observation corresponding supercritical influence side walls or air bubbles. behavior in an additionally applied magnetic reveals wall structure and permits determination value sign two coefficients bend e 3x splay 1z, when total coefficient ( z, + 3x) are known.
