Abstract
The electrooptical holographic grating formation effects in C60 and its derivative-doped nematic liquid crystal films were studied. C60 exhibits photoconductivity and photorefractivity effects generated in planar or homeotropic aligned nematic films. Three mechanisms for space charge field formation have been identified: the usual photorefractive effects, and the Carr-Helfrich effect associated with the liquid crystal's dielectric and conductivity anisotropies. Permanent holographic gratings written in nematic films can be turned on and off with an applied ac field via linear electro-optical effect.
