Abstract
A method of making a single crystal Ga*N article, including the steps of: providing a substrate of crystalline material having a surface which is epitaxially compatible with Ga*N; depositing a layer of single crystal Ga*N over the surface of the substrate; and etchably removing the substrate from the layer of single crystal Ga*N, to yield the layer of single crystal Ga*N as said single crystal Ga*N article. The invention in an article aspect relates to bulk single crystal Ga*N articles, such as are suitable for use as a substrate for the fabrication of microelectronic structures thereon, and to microelectronic devices comprising bulk single crystal Ga*N substrates, and their precursor structures.
