SGGG EPI 1SP Single Crystal Substrates - 3 Inch Diameter, 12.505 Å Lattice Constant for Magneto-Optical Films
Substituted Gadolinium Gallium Garnet (SGGG) EPI 1SP single crystal substrates are premium materials specifically engineered for magneto-optical film applications. These high-quality substrates feature calcium, magnesium, and zirconium substituting ions, making them ideal for bismuth-substituted iron garnet epitaxial film growth.
- Liquid epitaxy substrates for magneto-optical films
- YIG (Yttrium Iron Garnet) film growth
- BIG (Bismuth Iron Garnet) film development
- Advanced optical and electronic applications
Our SGGG crystals are grown using the Czochralski method with precise lattice parameter control and superior surface polish finishing, ensuring perfect epitaxial growth conditions.
