Dimensional crossover of the phase diagram in ferroelectric smectic free standing films
Demikhov E.I.
Qualitatively new for liquid crystals phase diagram of surface melting type has been observed in free standing films: the SmC* Sm C^erri and Sm C/errt-SmC^ phase transitions are shifted to lower temperatures by decreasing the number of layers. This phenomenon is explained by the influence of the depolarizing fields.
