Microstructure and defect characteristics of lithium niobate with different Li concentrations

Kunfeng Chen et al.

Summary: In this study, near-stoichiometric and non-stoichiometric lithium niobate powders were comprehensively investigated using X-ray diffraction, high-temperature Raman, and UV-vis spectroscopy. The results revealed that Nb antisites are the most stable point defect coexisting with Li vacancies in congruent lithium niobate samples. The intrinsic point defects induced Li/Nb cation mixing, temperature-dependent defect microstructures, and disorder in the lattice frame of lithium niobate.
