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.
