Spontaneous polarization-vector-reorientation photorefractive effect in ferroelectric liquid crystals
The photorefractive effect of a ferroelectric liquid crystal doped with a photoconductive compound was investigated. The photorefractive effect appeared only at the temperature at which the sample exhibits ferroelectricity. The refractive index grating formation time was measured to be {similar_to}30ms. In the ferroelectric phase, reorientation of the spontaneous polarization vector was found to be induced by the internal space-charge field. {copyright} 2001 American Institute of Physics.
