PHYSICAL REVIEW LETTERS – Volume: 110; Issue: 5; Article Number: 057801; DOI: 10.1103/PhysRevLett.110.057801

We study the pattern formation of a chiral nematic liquid crystal under a wetting transition. In the isotropic-liquid crystal transition, a surface-enhanced effect happens and a thin liquid crystal layer forms at the […]
