Photoinduced effects in the vicinity of the smectic-C(*)(alpha)-smectic-A transition.
We report the first results of photoinduced effects near the smectic-C(*)(alpha)-smectic-A transition in a binary liquid crystalline material. Dielectric dispersion measurements show that the softening of the tilt fluctuation mode in the vicinity of the transition gets enhanced in the presence of the UV light.
