EXAFS evidence for a primary Zn Li dopant in LiNbO 3
We present extended x-ray-absorption fine structure (EXAFS) data as a function of temperature (10-300 K) at the Zn and Nb K edges for Zn-doped LiNbO 3. The focus is on higher Zn concentrations (7-11mol%) for which there is disagreement in the literature as to the substitution site for Zn. Our data show that Zn substitutes only on the Li site; we find no evidence for Zn on the Nb site. However, uncertainties result in an upper bound of at most 5% of the Zn dopants being Zn Nb. In addition, the...[Show more]
