Surface electroclinic effect on the layer structure of a ferroelectric liquid crystal
Abstract
Optical second-harmonic generation and ellipsometry were used to study molecular alignment in an interfacial region and the deviation of the layer normal from the surface-rubbing axis in the smectic-A phase of a ferroelectric liquid crystal. The results can be well explained by the surface electroclinic effect. © 1992 The American Physical Society.
