Influences of surface and flexoelectric polarization on the effective anchoring energy in nematic liquid crystal |
Variations of the effective anchoring strength with applied voltage. The material parameters of LC are k 11 = 13.2 pN, k 33 = 18.3 pN, are Δ ε = 4.8. The thickness of NLC cell is l = 10 μm. Panels (a), (b), and (c) correspond to the three sets of parameters respectively, as given in the text. |
