Flexoelectrically Driven Electroclinic Effect in the Twist-Bend Nematic Phase<? format?> of Achiral Molecules with Bent Shapes
We extend the twist-bend nematic (N TB) model to describe the electro-optics of this novel
phase. We predict an electroclinic effect (ECE) subject to a dc electric field E applied …
