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 NbLi5+ should be involved in the charge transport process, while the Li vacancy VLi 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.
