GGG monocrystal Substrate
GGG (Gd₃Ga₅O₁₂) single crystal substrates are widely used in optical and electronic devices due to their excellent mechanical strength, thermal conductivity, and optical transparency. They are commonly employed in magneto-optical devices, microwave applications, and laser materials. GGG substrates are particularly suited for the epitaxial growth of YIG (Yttrium Iron Garnet) films and are used in spintronics and optical communication systems.
