Fabrication of square array of Smectic Liquid Crystal Defects by Multidirectional Rubbing |
| 초록 |
The smectic liquid crystal phase has a layered structure which has an additional positional order as well as orientational order. With antagonistic anchoring conditions (random planar at the substrate interface and homeotropic at air interface) smectic-A liquid crystals form toric focal conic domains (TFCDs). In previous research, our group achieved highly ordered hexagonal array of TFCDs with confined micro-channels and surface treatment. Controlling the arrangement of TFCDs is requirement for a new type of building block based on smectic liquid crystal. In this study, we introduce multi-directional rubbing method for square array of TFCDs. We could obtain square array of TFCDs by perpendicular directional rubbing. We searched the range of optimal rubbing strength condition about two perpendicular directions and investigated formation mechanism of square array of TFCDs. |
