| Abstract: | The influence of the surface-induced smectic A (SmA) phase on the threshold field, for homeotropic alignment of polar liquid crystals is discussed from the energy point of view. It is shown that the Freedericksz critical field, for 4-n-octyl-4'-cyanobiphenyl (8CB), in a very thin cell near the second-order nematic-SmA phase transition, exhibits an anomalous increase with decreasing of temperature. |
