摘要：

The use of ac stabilization in ferroelectric liquid-crystal (FLC) devices is commonplace: It enhances the bistability and increases the extinction angles seen in a cell. The mechanism involved in this process is investigated here. Examining the optic tensor profile across an ac-stabilized FLC layer has revealed that it is very similar to that present under a forward bias dc field. Comparing the dc/dipole and ac/dielectric interaction energies shows conclusively the presence of biaxiality in the dielectric tensor. This biaxiality is measured through the comparison of the ac and dc electric energy densities in a cell.
