| Abstract: | The angular dependence of the surface anchoring energies of the smectic C with temperature independent tilt angle (type C1) on two surfaces, SiO x /ITO/glass and holographic diffraction grating, were measured using a twist-cell method. The smectic C monodomains rotation, starting at a critical imposed bulk twist, revealed a surface anchoring breaking. The surface anchoring strengths of the SiO x /ITO/glass and holographic grating were evaluated. A model for the bulk twist influence on the smectic C monodomain growth was suggested. |
