23_46i/2011Epitaxial Assembly: Pillar-Assisted Epitaxial Assembly of Toric Focal Conic Domains of Smectic-A Liquid Crystals (Adv. Mater. 46/2011)

Randall D. Kamien, Shu Yang, and co-workers demonstrate an epitaxial approach to tailor the size and symmetry of toric focal conic domain (TFCD) arrays over large areas by exploiting 3D confinement and directed growth of Smectic-A liquid crystals using SU-8 pillar arrays with variable dimensions (size, height, and spacing) and sym-metries. As reported on page 5519, a new variety of TFCD arrays (e.g., square lattices) are obtained beyond the close-packed hexagonal arrangement formed spontaneously on a flat surface.
