In order to improve the knowledge of the domain structure in LiNbO crystals, the effect of the etching process with HF : HNO (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.

Abstract
In order to improve the knowledge of the domain structure in LiNbO crystals, the effect of the etching process with HF : HNO (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.File in questo prodotto:
