摘要:
On applying an appropriate electric field to a thin sample of ferroelectric liquid crystal a texture of long domains appears perpendicular to the smectic layers. We present observations showing that such treatment of the cell leads to its perfect bistability (i.e. a memory effect). The analysis of the equilibrium equations describing smectic liquid crystal elasticity shows how the director orientation is fixed both by a bulk deformation caused by the electric field treatment and by surface anchoring.
