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.
