Electric-field effects in the twist-bend nematic phase
In the recently discovered Twist-Bend Nematic (NTB) phase, the nematic director is spontaneously distorted and twisted along a conical helix with an extremely short pitch, ~10 nm. We have investigated the behavior of the NTB phase subject to an electric-field. We show that, due to the periodic NTB structure, the electro-optic effects are not nematic-like but are close analogs to those in the smectic and cholesteric phases. In particular, we have studied the fast (sub-microsecond) flexoelectrically- induced rotation of the optic axis, which is similar to the electroclinic effect in the SmA* phase and the flexoelectric response of short-pitch cholesterics. We discuss the possible applications of the fast NTB electro-optic effects.
