ResumoAbstract The liquid phase epitaxy technique has been shown to be successful for developing Nb 5+ -rich and Na + -modified LiNbO 3 films using various flux systems. X-ray diffraction studies showed that the films had a high single crystallinity, and the unit cell a A increased from 5.143 A for the Li + -rich LiNbO 3 to 5.155 for Na + -modified LiNbO 3 films, ranging from 10 to 30 μm thickness, showed a reduction in the temperature coefficient of surface acoustic wave (SAW) velocity; the improvement is almost 40%.
