Competition of elasticity and flexoelectricity for bistable alignment of nematic liquid crystals on patterned substrates.

Adler, James H.
Atherton, Timothy J.

We show that patterned surfaces can promote bistable configurations of nematics for reasons other than the symmetry of the surface. Numerical and analytical calculations reveal that a nematic liquid crystal in contact with a striped surface is subject to the competing aligning influences of elastic anisotropy, differing energy cost of various types of deformation, and flexoelectricity, curvature-i... read more
