| Popis: | The effect oxidizing annealing has on the electrical properties of nominally pure congruently grown LiNbO3 crystals is investigated via impedance spectroscopy. A set of samples is preliminarily reduced in saturated D2O or H2O vapor. It is shown that reducing annealing in saturated water vapor at T = 773 K results in partial deprotonation of LiNbO3 crystals. It is assumed that such annealing does not change the charge state of impurity ions with variable valence. |
