PMNT/PIMNT

PMNT and PIMNT are the next generation of high-performance optoelectronic materials with piezoelectric properties: d33 > 2000pc / N, k33 > 92%.

 

Application: Piezoelectric material is the energy conversion element of ultrasonic transducer, which is widely used in industry, agriculture, transportation, life, medical treatment, military and many other fields.

 

Technical Features

PMNT and PIMNT have excellent performance, which can greatly improve the sensitivity and bandwidth of the transducer and improve the quality of ultrasonic imaging.

 

Performance index: The phase transition temperature and coercivity field of the developed product are improved, which expands the temperature application range of relaxor ferroelectric crystals and allows the device to be used in strong field;

Electromechanical coupling coefficient k33 up to 0.94; Field induced strain s > 1.7%; The piezoelectric coefficient d33 is about 4 ~ 5 times higher than PZT, and the dielectric loss is 1 ~ 3 lower.

 

Prospect: It has a complete process for growing large-size, high-quality and high-performance relaxor ferroelectric crystal pimnt, and can provide single crystals of different sizes (2 inches, 3 inches and 4 inches) on a large scale according to the application requirements.

Uses/Applications

Ferroelectrics materials show high performance for optical applications such as optical modulation, light generation, optical filtering, and nanophotonic components. Periodical domainengineered ferroelectric crystals with second-order nonlinearity create a valuable class of nanostructure to realize quasiphase matching. They have been applied in laser frequency conversion, generation of entangled photons, and optical solitary wave devices.
