Strontium Titanate Single Crystals（Furuuchi Chemical）
Summary
It is possible to control the carrier concentration and transmittance by doping, and this product is expected to contribute as a key device for optical networks with large capacity, ultra-high speed, and low power consumption.
Application Examples
Optical switches with PLZT thin film fabricated on Nb-doped SrTiO3 single crystal substrates can achieve lower control voltage, faster response, and lower polarization dependence, leading to increased capacity, ultra-high speed, and low power consumption of optical networks.
＊PLZT：Pb1-xLa（x ZryTi1-y）1-x/4O3
Benefits for Customers
- Carrier concentration and transmittance can be controlled by Nb or La doping.
- Larger crystals with a 2-inch diameter are expected to enable larger devices.

FAQ
What sizes are available?
-
The standard size is 10 mm x 10 mm, but we are working on increasing the size by growing large crystals, so please feel free to contact us.
Are Nb and La the only elements that can be doped?
-
Nb and La are the standard, but please contact us to discuss the possibility of doping other elements as well.
