Surface Induced Phase Separation and Pattern Formation at the Isotropic Interface in Chiral Nematic Liquid Crystals

Rafael S. Zola, Luiz R. Evangelista, Y.-C Yang e D.-K. Yang

Physical Review Letters – Volume: 110; Issue: 5; Article Number: 057801; DOI: 10.1103/PhysRevLett.110.057801; 2013

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 […]
