Ultraviolet light‐emitting diode of a cubic boron nitride pn junction made at high pressure

Injection luminescence in the ultraviolet is observed from a cubic boron nitride pn junction diode made at high pressure. Microscopic observation and spectroscopic studies show that the light emission occurs near the junction region only in the forward‐bias condition. The spectra extend from ∼215 nm to the red, having a few peaks mainly in the ultraviolet.
