Abstract: A device includes a substrate (10) and a III-nitride structure (15) grown on the substrate, the III-nitride structure comprising a light emitting layer (16) disposed between an n-type region (14) and a p-type region (18). The substrate is a RA03 (MO)n where R is one of a trivalent cation: Sc, In, Y and a lanthanide; A is one of a trivalent cation: Fe (III), Ga and Al; M is one for a divalent cation: Mg, Mn, Fe (II), Co, Cu, Zn and Cd; and n is an integer?1. The substrate has an inplane lattice constant asubstrate. At lease one III-nitride layer in the III-nitride structure has a bulk lattice constant alayer such that [(|asubstrate?alayer|)/asubstrate]*100% is no more than 1%.

Abstract: In a method according to embodiments of the invention, a III-nitride layer is grown on a growth substrate. The III-nitride layer is connected to a host substrate. The growth substrate is removed. The growth substrate is a non-III-nitride material. The growth substrate has an in-plane lattice constant asubstrate. The III-nitride layer has a bulk lattice constant alayer. In some embodiments, [(|asubstrate?alayer|)/asubstrate]*100% is no more than 1%.
