SrTiO3 single crystal is used for epitaxial growth and most oxide films
SrTiO3 (Strontium Titanate), a perovskite oxide with exceptional physical properties, is a cornerstone material in the field of solid-state physics and electronics. Its single-crystal wafers exhibit remarkable dielectric, ferroelectric, and superconducting characteristics, depending on the temperature and doping conditions. These wafers, meticulously grown through techniques such as flux growth or pulsed laser deposition, offer unparalleled crystallinity and surface smoothness, essential for high-performance devices.
SrTiO3 wafers are highly sought after for their applications in advanced electronics, including gate dielectrics in field-effect transistors, capacitors in dynamic random-access memory, and even as substrates for the growth of complex oxide heterostructures. Their tunable properties and compatibility with various deposition techniques make them versatile building blocks for the next generation of microelectronics and quantum technologies. The pursuit of perfecting SrTiO3 wafers continues to drive innovation in materials science and solid-state engineering.

FAQs:
A: We look at ourselves as the piezo wafer specialist. We are the very first to work with Single Crystal Quartz in China about 30 years ago. Then gradually we step in the field of LiNbO3, LiTaO3, Quartz glass, LGS, CTGS etc. Especially, if you are looking for a piezo quartz supplier, we are the ultimate choice! We export millions of quartz blanks each year because we master the AT, SC and IT cuts with superior angle precision.
A: Yes, of course. We can fabricate as per your request. In addition, we are so experienced with piezo wafers that we can provide you relevant suggestions if you are not 100% sure about your choice. Besides, we do have some standard wafers in stock, please check with us.
A: Yes, we would suggest you go with the courier agent you are most familiar with (DHL, FedEX, UPS etc.). We can ship via your account. And, of course, we will pack the products safely in acceptable size to help you save the shipping cost. If you need us to take care of the freight, it’s also not a problem. We also have good discount with the international courier companies.
A: The wafer products are fragile and sometimes expensive. The last thing, as the manufacturer, we want to see is the products we make were damaged during courier. As a result, we will pack the wafers adequately and put them in a proper carton filled with buffer sponge. However, accidents are inevitable sometimes. So, please follow the “Acceptance check” steps shown in the drawings below. If the unwanted happened, we will either give the replenishment or refund if you follow the checking steps.
