Christophe Didier, Manager of Soitec's filter business, explained the technology and market prospects of POI substrates to industry media, including the electronics enthusiast network, in a recent media briefing.
With the advancement of technology, the output of quartz crystals in China has maintained a growth trend. In 2023, the output of quartz crystals in China reached nearly 3,000 tons, up nearly 10% year-on-year. Abundant supply of raw materials will lay a solid foundation for the development of China's piezoelectric quartz crystal industry.
1. Lithium niobate crystal: superior performance, mainly used in optoelectronic field Lithium niobate crystal has the characteristics of high photoelectric effect and strong performance adjustability. Lithium niobate (LiNbO3) is a compound of niobium, lithium, and oxygen, and is a negative crystal with a large spontaneous polarization (0.70 C/m2
The introduction of "new infrastructure" has gradually brought 5G into our lives, and with it, the development of cloud computing, virtual reality, data communication, and high-definition video has been continuously advancing, driving the core optical network to upgrade towards ultra-high speed and ultra-long distance transmission. In this process,
The Czochralski method has advantages such as fast crystal growth rate, flexible control of crystal growth conditions, and reduced crystal defects, making it the mainstream preparation method for lithium tantalate crystals.
