Abstract:
Fabrication of a heterostructure, such as a group III nitride heterostructure, for use in an optoelectronic device is described. The heterostructure can be epitaxially grown on a sacrificial layer, which is located on a substrate structure. The sacrificial layer can be at least partially decomposed using a laser. The substrate structure can be completely removed from the heterostructure or remain attached thereto. One or more additional solutions for detaching the substrate structure from the heterostructure can be utilized. The heterostructure can undergo additional processing to form the optoelectronic device.

Claim (Index 1):
A heterostructure comprising:\n a substrate structure including:\n a substrate; and \n a set of group III nitride buffer layers directly adjacent to the substrate; \n a set of group III nitride device layers located adjacent to the substrate structure; and a sacrificial layer located between the substrate structure and the set of group III nitride device layers, wherein the sacrificial layer includes at least one sublayer including a first set of regions formed of a first material and a second set of regions located laterally adjacent to the first set of regions and having a composition different from the first material, wherein the first material has a bandgap smaller than a bandgap of each of the set of group III nitride buffer layers and the set of group III nitride device layers.
