  • Influence of the inhomogeneous surface pretilt on zig-zag defectss
    Kralj, Samo ...
    The influence of the inhomogeneous surface pretilt (slope) on chevron structures and on zig-zag defects in a SmC liquid-crystal cell is stuied. The experimentaly observed effect of the confining ... substrate with controlled variation of the surface slope on the formation of zig-zag defects is qualitatively explaned with the Landau-Ginzburg-type free-energy expanded in terms of the nematic director field and the smectic complex order parameter. Transitions in the C1 and C2 chevron structures are studied as functions of the surface pretilt angle ▫$Phi(t)$▫ . The threshold conditions are calculated. The width of the straight element of the domain wall (running parallel to the smectic layers) and the costs for its formation are estimated
