ALUMINUM NITRIDE CRYSTALS HAVING LOW URBACH ENERGY AND HIGH TRANSPARENCY TO DEEP-ULTRAVIOLET WAVELENGTHS
In various embodiments, single-crystal aluminum nitride boules and substrates have low Urbach energies and/or absorption coefficients at deep-ultraviolet wavelengths. The single-crystal aluminum nitride may function as a platform for the fabrication of light-emitting devices such as light-emitting d...
