The Influence of Annealing in Saturated Water Vapor on LiNbO3 Crystals Optical and Electrical Properties
The temperature dependence of the dark electrical conductivity of the LiNbO3 (LN) 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 and is close this value of LN samples, reduced in hydrogen. Annealing in ampoules with H2O vapor also lead to LN optical spectra changes such annealing in H2. The nature of this phenomenon is discussed.
