The Mathematics of Liquid Crystals

The epitaxial assembly of toric focal conic domain (TFCD) arrays of smectic-A liquid crystals onto pillar arrays is studied. The 3D nature of the pillar array is crucial to confine and direct the formation of TFC Ds on the top of each pillar and between neighboring pillars, leading to highly ordered square and hexagonal array TFC Ds persisting deeply into the bulk.
