Abstract
Described herein are rock salt substrates and methods of making thereof that are useful as epitaxial substrates for semiconducting materials, including ultra-wide bandgap materials. Advantageously, the described rock salt substrates may be useful as substrates for Group III (Al, Ga, In)—N substrate allowing for pseudomorphic growth of novel, desirable materials. The rock salt may be provided as a bulk material or deposited as a thin film. These substrates may allow for generation of high Al content semiconductor devices with ultra-wide bandgap and other useful properties.
