摘要: We have created periodic lattices of close-packed non-toroidal focal conic domains (FCD) in smectic A liquid crystal films deposited on solid substrates that induce unidirectional planar anchoring, at the interface with air which induces homeotropic anchoring. Each cell of the quasi-hexagonal lattice contained a FCD with an eccentric ellipse aligned with the planar anchoring direction and tilted from the solid substrate towards the free interface. In contrast to common toroidal FCDs, the ellipse was truncated by both the substrate and the free …
