Abstract

We present a detailed discussion of the fundamental mechanisms for recently observed persistent photorefractive effects in nematic liquid crystal films. A theoretical analysis of the various space charge fields, dielectric torques, and estimates of their magnitudes and critical assessment of their roles in the observed holographic grating formation process are presented. In dye- or Fullerene C 60-doped films, it is observed that the induced director axis and refractive index grating could persist indefinitely. Furthermore, these stored gratings can be electrically switched on and off at ms-subms speed.
