Flexoelectric surface switching of bistable nematic devices

Abstract:
A new method of dynamically controlling the boundary conditions of a nematic liquid crystals was studied using surface flexoelectric effect. Switching between the states occurs when the movement of the surface directors rotates those in the bulk, which are then able to create or annihilate defects. The results showed that the driving force that causes the switching is a surface flexoelectric effect.
