MgAl6O10
MgAl6O10 single crystal is a new substrate material for GaN and ZnO epitaxial growth. MgAl6O10 single crystal belongs to cubic system, the space group is fd-3m (227), the cell parameter a = 7.9780 Å, and its density is 3.585g/cm3. Compared with MgAl2O4 crystal, MgAl6O10 single crystal has smaller thermal expansion mismatch and lattice mismatch with GaN. The thermal expansion mismatch with GaN is 2.2 × 10 − 6 K − 1, lattice mismatch is − 11.5%. In addition, MgAl6O10 single crystal is easier to grow large-size and high-quality crystals because its melting point is lower than that of MgAl2O4 crystal. Experiments show that the luminescence performance of GaN and ZnO devices prepared on MgAl6O10 single crystal substrate is better than that of sapphire.CasCrysTech (CCT) provides high quality MgAl6O10crystals upon request from customers.
