1. Lin, Sin-an. Study of lattice plane control of blue phase II liquid crystal.

Degree: Master, Electro-Optical Engineering, 2017, NSYSU

Blue phase liquid crystal is a class of liquid crystal phases in chiral nematics, featuring self-assembled three-dimensional photonic crystal structure. The optical and electro-optical characteristics vary with lattice orientations. There have been a few reports on the properties and applications of photonic crystals with different orientations. However, a comprehensive discussion about how the lattice orientation can be controlled has yet been presented. Recently, our group also develops a gradient-temperature technique to grow blue phase liquid crystal into large single crystal form. The surface alignment assists in guiding the crystal growth in a specific orientation. In this study, we successfully grow a (100)-oriented blue phase by applying an electric field on an ITO-coated glass without alignment layers. In a homogeneous aligned cell, we successfully control the lattice orientation to (100) or (110) by change the pitch. We find the direction of (110)-oriented blue phase has a significant relation with the direction of rubbing on substrates. If we use anti-rubbing homogeneous-aligned cell, it has two blue phase structures in the bulk due to the influence of rubbing. The lattice orientation of (110) has a GMR-like characteristic and has the effect of splitting, and the position of the two reflection wavelengths can be shifted by adjusting the angle of the incident light. The lattice orientation is independent of a cell gap because the blue phase liquid crystal grow from the surfaces of the substrates. In a homeotropic-aligned cell, we successfully induce (111)-oriented and the orientation in independent of a cell gap and a pitch. In a hybrid cell, the final lattice orientation depends on the direction of the crystal orientation of the upper alignment layer.
