Liquid crystal topological defects at the nanoscale precision

We will study topological defects in smectic liquid crystals at the scale of a single defect or a very small number of defects, using nano-diffraction on a thin film (8CB...本研究将在单个缺陷或极少量缺陷的尺度下，对层状液晶（smectic liquid crystals）中的拓扑缺陷（topological defects）展开研究，实验方法为借助薄膜（8CB……）上的纳米衍射（nano-diffraction）技术。
