| Abstract: | Using the molecular field approximation, liquid crystal films on the unrubbed substrates are studied by Lebwohl-Lasher model. We have given the molecular orientational states of liquid crystal films for the nematic phase and the nematic-isotropic phase transition. We have also discussed the orientational order induced by the substrates, including biaxial order, and biaxialuniaxial phase transition in the surface region. |
