Abstract

The temperature dependence of the dark electrical conductivity of the LiNbO₃ crystals annealed in saturated H₂O and D₂O vapor in the range 293...400 K is investigated. It is found that the activation energy of the electrical conductivity is equal to (0.71 ± 0.02) eV. This value is similar to the activation energy of the H₂-reduced LiNbO₃. Annealing in ampoules with H₂O vapor also leads to LN optical spectra changes similar to the annealing in H₂. The nature of this phenomenon is discussed.
