Abstract:
Using the results of studying the electrical conductivity in the temperature range of $\sim$295–460 K and the IR absorption spectra of a series of LiNbO$_{3}$: Mg crystals, it is shown that as the Mg content in the sample increases, the mobility of H+ ions sharply decreases when moving along the polar direction. This effect is most clearly manifested in the samples of LiNbO$_{3}$: Mg crystals with a high (above threshold value) impurity content.
Keywords:
ferroelectrics, lithium niobate, electrical conductivity, mobility, doping, impurities.
