Molecular Formula	ScAlMgO4

More info

Magnesium Aluminate Scandium Oxide (ScAlMgO4) Crystal Substrate is a newly developed substrate material optimized for GaN and ZnO heteroepitaxial growth. Belonging to the hexagonal crystal system with lattice parameters a = 0.3246 nm and c = 2.5195 nm, it features a rhombohedral layered structure similar to wurtzite nitrides and ZnO. With a lattice mismatch of approximately 1.8% for GaN and just 0.09% for ZnO, it provides superior structural compatibility. Additionally, its thermal expansion coefficients (6.2×10⁻⁶/°C along the a-axis and 12.2×10⁻⁶/°C along the c-axis) ensure better thermal matching compared to conventional sapphire and silicon substrates. Heeger Materials provides high-quality ScAlMgO4 Crystal Substrate to support various semiconductor and optoelectronic applications.
