Lithium niobate single crystal thin film is currently in the sound surface wave and body wave device
production aspects, such as a crystal is widely used. Confirmed by laser probe study, Y41 ° lithium niobate single crystal in this direction with excellent surface acoustic potter leakage resistance, the surface acoustic wave leakage electromechanical coupling coefficient (about 1. 7.2%), low transmission loss and good temperature coefficient device made in great attention. Y41 ° lithium niobate single crystal growth, changed by rotating cutting axle, Y 1 2 8 ° c lithium niobate crystals, are Y41 ° lithium niobate substrate of the status quo, improve the utilization rate of crystal and cutting processing more convenient and reliable, more effectively meet the requirements of surface acoustic wave devices is leakage. This research adopts the resistance heating pulling method growth Y41 ° lithium niobate single crystal, draw lessons from my other direction lithium niobate single crystal growth in the mature process measures, after much furnace experiment, design a suitable Y41 ° lithium niobate single crystal growth temperature field structure, find the suitable temperature gradient (2, 0 ~ 1 0 0 ℃ / cm) on growth, and determine the corresponding key process parameters, solved the Y41 ° lithium niobate single crystal growth, the twin is seen, the tail is easy to distort, easy cracking and other technical issues, success grows out of 77 mm x 70 mm macro integrity good quality Y41 ° lithium niobate single crystal.
