N2 - We achieved high-speed solution growth of AlN single crystal from Cr-Co-Al solvent, which was designed on the basis of thermodynamic calculation. To avoid the unintentional precipitations at the interface between solution and gas as well as to increase the growth rate, we designed the solution growth condition, in which the solution near the interface is undersaturated and the solution near the growth position is supersaturated. To realize this kind of ideal condition, we selected Co and Cr as solvent materials due to their high affinity with nitrogen or aluminum. Finally, we achieved a growth rate as high as 200 μm/h in maximum.
