CURRENT INJECTION DIAMOND ULTRAVIOLET LIGHT EMITTING DEVICE

摘要

A current injection-type diamond ultraviolet light-emitting device is provided that achieves the diamond free exciton recombination radiation by forming electrodes on a high-quality diamond crystal and applying a DC voltage between both electrodes to inject carriers. A diamond crystal can be selected in terms of photoluminescent spectrum at room temperature and the half width of the Raman scattering peak intrinsic to the diamond.
