Nonplanar structure of molecular tilt planes in the surface layers of smectic-A free-standing liquid crystal films.
We present ellipsometric results from thin free-standing films of one chiral liquid crystal compound. In the bulk SmA range with surface-induced molecular tilt, a nonplanar arrangement of the molecular orientations of the tilted surface layers is found under a small applied electric field.
