摘要：

In order to improve the knowledge of the domain structure in LiNbO3 crystals, the effect of the etching process with HF:HNO3 (1:2 by vol.) has been studied. It has been found, by analyzing the superficial composition with the secondary ion mass spectrometry technique, that during the etching treatment, the fluorine ion diffuses into the crystal, mainly along the positive ferroelectric domain.
