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-induced ... read more
