LiNbO3

Lithium niobate is an excellent piezoelectric transducer material, ferroelectric crystal, and photoelectric material; as an electro-optic material, it plays a role in optical modulation in optical communication and is widely used in parametric oscillators, frequency doublers, acousto-optic devices, and optical modulators. Polarized lithium niobate crystals have good piezoelectric, ferroelectric, photoelectric, nonlinear optical, and thermoelectric properties, and also exhibit a photorefractive effect.
