Abstract

In this paper, we analyze the characters of all damage- resistant dopants' valences and electronic shell configurations found up to now in LiNbO₃ crystals. We show that all damage-resistant dopants have only one valence state. We also show that these damage-resistant ions' electronic shell configurations are filled fully, as are the cases of the inert elements. From this point of view, we conclude that the anti-site Nb_Li⁵⁺ should be involved in the charge transport process, while the Li vacancy V_Li is not involved in the charge transport process. It also can give us some insights about how to select a damage-resistant dopant for LiNbO₃ crystal.
