Abstract
To determine the defect structure of ZnO-doped LiNbO3 single crystals with high doping concentrations, we obtain the measurements using the extended x-ray absorption fine structure (EXAFS) at room temperature. It indicates Zn atom is directly substituted on the Li site of the LiNbO3 crystal after Zn doping. EXAFS simulation by way of analyzing the scattering amplitudes also shows that the Zn atom does not substitute the Nb site at highly Zn-doped LiNbO3. Finally, we confirm that VNb5−, a strong charged vacancy, should be considered as an important factors in influencing the physical properties of LiNbO3 beyond 7.5mol% Zn-doped doping concentration.
