Liquid-phase-epitaxial growth of single-crystal LiNbO3 thin film

Abstract

The phase equilibrium of the LiVO3-LiNbO3 pseudobinary system has been investigated, and a LiNbO3 single-crystal thin film has been grown epitaxially onto the substrate by dipping a c-plate LiTaO3 substrate into a LiVO3 flux solution. An x-ray rocking curve indicated that the film had a high single crystallinity with good epitaxy. The composition ratio Li/Nb of the film was estimated to be close to the stoichiometric value Li/Nb≈1.0.
