Claim of US Patent No. 9,991,414

1. A method comprising:growing a III-nitride layer with a bulk lattice constant alayer on a non-III-nitride growth substrate with an in-plane lattice constant asubstrate such that [(|asubstrate?alayer|)/asubstrate]*100% is no more than 1%;
providing a composite substrate comprising the III-nitride layer bonded to a host substrate; and
growing a semiconductor structure comprising a light emitting layer disposed between an n-type region and a p-type region on the III-nitride layer of the composite substrate.
