摘要：

We present an elastic model to explain the temperature-induced surface transitions observed on the spontaneous orientation of nematic liquid crystals on solid surfaces. The destabilizing effect is due to the mixed splay-bend curvature elasticity K13. The transition is temperature driven by the change in the nematic-liquid-crystal order parameter S. The transition is continuous. A large angular variation localized close to the boundary is predicted. Analyzing experimental data, we estimate \K13\ is-approximately-equal-to 10(-7) cgs units.
