Abstract

Within the framework of the phenomenological model that takes into account the interactions between the smectic layers explicitly, we analyze the structure, the transition temperatures and the macroscopic polarization of the free standing film formed by an antiferroelectric liquid crystal. Outer layers of the film interact only with the interior of the film and are therefore less tilted. Consequently, the transition temperatures from the tilted phase to the untilted smectic. A phase are lower than for bulk samples. Due to the chiral interactions the film possesses the macroscopic polarization which is for even lower than for bulk samples. Due to the chiral interactions the film possesses the macroscopic polarization which is for even number of layers parallel to the plane of the tilt, while for odd number of layers it is nearly perpendicular to the plane of the tilt.
