Abstract
We provide direct evidence, using simultaneously total internal reflection and polarized optical microscopy, for the existence of two interface stabilized director n-polarization P orientation states at a ferroelectric liquid crystal (FLC)-solid interface. The states are separated by a first-order orientation transition, having n nearly parallel to the surface, opposite orientations of the component of P normal to the surface, with the state having P directed into the FLC being of lower energy. Any unswitched layer is less than 20 Å in thickness.Keywords
