Outline

Topological defects in nematic liquid crystals are singular points in the director field with properties different from the bulk. The creation of complex-shaped defects often involve confining the liquid crystals in complex-shaped geometries; in this project, three-dimensional defect networks will be constructed through surface orientation control in a slab-type liquid crystal device. The optical and electrical properties of the defect networks will be investigated for potential application as smart windows with ultra low-power consumption.
