Abstract:

Photoinduced charge transport in lithium niobates is defined by presence of a iron-like impurity, Fe2 being the donor, Fe3 - the acceptor of electrons. Two level scheme gives the linear dependence of photoconductivity that is of inverse response times of photorefraction on the light intensity. We discuss the influence of Me impurities Me Mg,Zn. provided for optical damage resistance in LiNbO3, on photoelectric phenomena. Me impurity affects photoconductivity of LiNbO3 rather than photovoltaic properties. Investigations of charge transport phenomena in LiNbO3 Me reveal some threshold Me concentrations 5.5 mol.Mg3 or 7.7mol.Zn4 which coincide with those in optical measurements.
