Abstract

See full text

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 diodes and lasers. The single-crystal aluminum nitride boules may advantageously have diameters that increase along at least portions of their lengths.
