向列相液晶中的位错具有重要的理论意义和实用价值。产生和重新配置连接基片上预定点的倾斜度的能力可以实现新的应用,例如微/纳米颗粒和分子的定向自组装。在这项研究中,我们提出了一种新的方法来设计和创建连接衬底上预定位置的错位互连。我们证明了这些互连可以通过用线偏振光重写光取向材料来在不同状态之间切换,并且可以利用电场在亚稳态之间切换。
Disclinations in nematic liquid crystals are of great interest both theoretically and practically. The ability to create and reconfigure disclinations connecting predetermined points on substrates could enable novel applications such as directed self-assembly of micro/nanoparticles and molecules. In this study, we present a novel approach to design and create disclination interconnects that connect predetermined positions on substrates. We demonstrate that these interconnects can be switched between different states by re-writing photoalignment materials with linearly polarised light and can be switched between metastable states using electric fields.
