  • Title: Polar anchoring strength of a tilted nematic: confirmation of the dual easy axis model.
    Author: Carbone G, Rosenblatt C.
    Journal: Phys Rev Lett; 2005 Feb 11; 94(5):057802. PubMed ID: 15783701.
    Abstract:
    The polar anchoring strength coefficient W and polar pretilt angle theta0 were measured simultaneously for the liquid crystal pentylcyanobiphenyl at a rubbed polyimide alignment layer that is ordinarily used for vertical alignment. It was found that W proportional theta(2)0 over the range 0 degrees < or =theta0 less or similar to 35 degrees . The results provide a confirmation of the dual easy axis model, wherein the liquid crystal director adopts an equilibrium orientation theta0 at the substrate that is determined by competition between a pair of preferred orientation directions.
