More info

SGGG Single Crystal Substrate is a specially modified gadolinium gallium garnet (GGG) crystal, incorporating calcium, magnesium, and zirconium as dopants to optimize its properties for epitaxial applications. While GGG substrates have been widely used in thin-film growth, their small lattice constant makes them unsuitable for high-bismuth-substituted iron garnet (BIG) epitaxial layers. The introduction of substitution ions in SGGG adjusts the lattice parameters, making it a more compatible and stable substrate for BIG thin films. It is widely used in magneto-optical applications and advanced thin-film research. Heeger Materials (HM) provides high-quality SGGG Single Crystal Substrate to meet the demands of various research and industrial applications.
