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, exibits an anomalous increase with decreasing of temperature.
