Crystal Substrates Magnesium Aluminate MgAl2O4 uses in optical, electronic applications
Breif introducation of Magnesium Aluminate MgAl2O4 Crystal Substrates
MgAl2O4 is a relatively low-cost substrate material, which has been successfully applied to the growth of high quality GaN films. MgAl2O4 is cleaved on the (100) plane.
GaN LD cavities have been obtained by simply cleaving MgAl2O4 substrates along the (100) direction, which will also work well for ZnO.
MgAl2O4 crystal is very difficult to grow, due to the difficulty in maintaining a single phase structure.
It is also found that MgAl2O4 is a good substrate for III-V nitrides device
