Smectic layer rotation in the smectic A phase of ferroelectric and antiferroelectric liquid crystals

Smectic layer rotation in the smectic A phase of ferroelectric and antiferroelectric liquid crystals has been observed by applying asymmetric voltage pulses. The layer rotates over the field-induced tilt angle due to the electroclinic effect. The rotation is reversible. Namely, the layer rotates in...

Summary:Smectic layer rotation in the smectic A phase of ferroelectric and antiferroelectric liquid crystals has been observed by applying asymmetric voltage pulses. The layer rotates over the field-induced tilt angle due to the electroclinic effect. The rotation is reversible. Namely, the layer rotates in the opposite direction upon applying pulses of opposite polarity. The electroclinic effect plays an important role in this phenomenon.
