| Outline of Final Research Achievements |
We demonstrated that the drastic reduction of the driving voltage (<1 order ~10V/10micro) by introducing the slippery interface of the liquid walls under interdigitated in-plane electrodes keeping the nature of the ultra-fast switching dynamics. Slippery interfaces are artificially designed and spontaneously realized by the macroscopic phase separation due to the solvent effects on the liquid crystals. Smooth motion of the C-director is originated by the lubrication of the molecular motion on the slippery liquid interfaces. We have identified the clear change of the mechanism of the electro-optic response of SmC* related to helix motion by analyzing the motion of the Cano’s wedge by polarizing microscope. We discussed about the switching dynamics of SmC* on the slippery interfaces both intra and inter helix unwinding/rewinding motions.
