Abstract

Aspects of the subject disclosure may include, for example, bonding III-Nitride epitaxial layer(s) to a carrier wafer, wherein the III-Nitride epitaxial layer(s) are grown on a non-native substrate, after the bonding, removing at least a portion of the non-native substrate from the III-Nitride epitaxial layer(s), processing the III-Nitride epitaxial layer(s) to derive an array of III-Nitride islands, establishing a metal layer over the array of III-Nitride islands, resulting in an array of metal-coated III-Nitride islands, arranging the carrier wafer relative to a host wafer to position the array of metal-coated III-Nitride islands on a surface of the host wafer, causing the array of metal-coated III-Nitride islands and the surface of the host wafer to eutectically bond, and removing the carrier wafer to yield an integrated arrangement of III-Nitride islands on the host wafer. Additional embodiments are disclosed.
