Y axis LT LN Single Crystals by CZ growth method
Y axis LT LN Single Crystals by CZ growth method
Lithium niobate is a ferroelectric crystal with a Curie point of 1140℃, a spontaneous polarization of 50×10C/cm' and a thermal conductivity of 0.056(W/cm·K). The deformed lithium niobate crystals have many properties, such as piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric, and photorefractive effect.
Application
The largest use of Lithium Tantalate (LT) and Lithium Niobate (LN) is in SAW devices mounted in communication devices. Many communication devices, such as smartphones are being used every day. When voice communication and data communication are performed, SAW devices such as SAW filters and SAW duplexers are mounted in communication devices as filters for preventing noise and interference.
