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.
