Comparative study of defect structures in lithium niobate with different compositions

Structure refinements were conducted on LiNbO 3 crystals with four different compositions, ranging from near stoichiometric ( Li (Li + Nb) = 0.498 ) to highly nonstoichiometric ( Li (Li + Nb) = 0.470 ), by the X-ray single-crystal diffraction and the TOF neutron powder diffraction methods to clarify...
