摘要

摘要:本文综述了近年来在不同形状的向列液晶(NLC)外壳上具有拓扑缺陷的结构的研究，以及利用外电场操纵这些结构的可能性。结果表明，边界面的主曲率对NLC壳上缺陷的数量和排列有很大的影响。研究还表明，外电场可以用来控制这些壳层上发生的价中心的数量，从而揭示它们作为纳米光子器件多价构建块的能力。

Defect structures in nematic liquid crystal shells of different shapes

ABSTRACT The present review is devoted to recent studies of structures with topological defects on nematic liquid crystal (NLC) shells of different shapes and to the possibility of using external electric fields to manipulate these structures. It is shown that principal curvatures of bounding surfaces have a strong effect on the number and arrangement of these defects on NLC shells. It is also shown that external electric fields can be used to control the number of valence centers occurring on these shells, thus unveiling their capability of acting as multivalent building blocks for nanophotonic devices.
