Polarization Reversal and Ferroelectric Domains in LiNbO3 Crystals,tching are discussed starting from the Landau-Guinzburg-Devonshire phenomenology with an account for a contribution from domains and domain walls. The concept of the internal bias fields . in ferroelectrics related to an interaction of defects with the host is presented. The Miller-Weinreich model o

Point Defects in LiNbO3,re antagonists of Nb antisites and strongly reduce the photorefraction, when doping above certain threshold concentrations. These dopants increase the phase transition temperature, the density and shift the bandedge absorption towards the UV. Many properties differ below and above the threshold conc

Problem of a Non-Erasable Photorefractive Hologram, form long-living metastable states resulting in slowing down the optical erasure. Another method providing a nonvolatile readout is the thermal fixation of gratings based on screening the recorded electronic space-charge by species of the opposite sign (ions or photoholes) activated when heating to
