Abstract (en)

[origin: WO2012059843A1] In a method according to embodiments of the invention, a Ill-nitride layer is grown on a substrate. The substrate is RA03(MO)n, where R is selected from Sc, In, Y, and the lanthanides; A is selected from Fe (III), Ga, and A1; M is selected from Mg, Mn, Fe (II), Co, Cu, Zn and Cd; and n is an integer = 1. In some embodiments, [(|asubstrate - alayer|)/asubstrate]* 100% is no more than 1%, where asubstrate is an in-plane lattice constant of the substrate and alayer is a bulk lattice constant of the III -nitride layer. In another method according to embodiments of the invention, a Ill-nitride layer is grown on a substrate. The substrate is a non-III-nitride material. The Ill-nitride layer is a ternary, quaternary, or quinary alloy. The Ill-nitride layer is thick enough to be mechanically self-supporting and has a low defect density.
