    Photorefractivity and Optical Wave Mixing Effects in Nematic Liquid Crystals Doped with Fullerene Derivatives and Dyes

    The photorefractive effect has been observed and documented for decades1,2. This effect is typically observed in impurity doped electrooptic crystals. When the crystal is illuminated, charge carriers are excited ...

    Photorefractivity and Holographic Storage Effect in Fullerene C60-Doped Nematic Liquid Crystals

    The results of a recent study of a nonlinear electro-optical effect in fullerene C6o-doped nematic liquid crystal film are presented. In particular, photo-induced conduction, self diffraction effect, and permanen...
