ABSTRACT
Optical recording in a ferroelectric liquid crystal using smectic layer rotation induced by the application of asymmetric voltage pulses has been proposed. This recording method is based on the temperature dependence of the rotation rate and the fact that the rate in the smectic A (SmA) phase is considerably smaller than that in the chiral smectic C (SmC[sup *]) phase. The transition from the SmC[sup *] to the SmA phase can be induced by the photothermal effect. The application of asymmetric voltage pulses during partial laser irradiation results in the patterning of the layer alignment. This recording method can erase and invert the stored pattern and can handle gray-level patterns. © 2002 American Institute of Physics.

    In this paper, we demonstrate an increase in the flexoelectro-optic response of a hypertwisted chiral nematic liquid crystal with the addition of a low concentration (0.7 wt %) of a fluorosurfactant so as to reduce the anchoring energy at the liquid crystal/substrate boundary. Specifically, the...

    We investigate both the supercooling and the hysteresis phenomena of the phase transitions between the smectic C* and the smectic CA* phases driven by temperature and electric field, respectively. These two phenomena show similar characteristics for the dependence of transmittance on both the...

    Monolayer graphene flakes were dispersed at low concentrations into two achiral liquid crystals (LCs) alkoxyphenylbenzoate (9OO4) and 4-cyano-4'-pentylbiphenyl (5CB), separately. The presence of graphene resulted in two types of chiral signatures in the LCs: an electroclinic effect (a polar tilt...
