Using the results of studying the electrical conductivity in the temperature range of ~ 295-460 K and the IR absorption spectra of a series of LiNbO3: 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 LiNbO3: Mg crystals with a high (above threshold value) impurity content.
The temperature dependence of the electrical conductivity and the primary pyroelectric coefficient of lithium niobate crystals LiNbO3 grown from a melt with K2O flux was investigated in the range of 292–450 K . It is shown that these crystals are characterized by a strong anisotropy of electrical conductivity, and in the temperature range studied, proton conductivity dominates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
