Realization of diamond or zinc oxide p-n junctions
Ultraviolet light-emission diodes
Research Overview
Diamond and zinc oxide had been regarded by researchers around the world as suitable materials for ultraviolet light emittion diodes due to their semiconducting properties. However, they were not put into practical use because p-n junctions could not be realized. The results of studies represent a breakthrough by these two CREST research teams. The realization of p-n junctions has been achieved both in diamond and zinc oxide, allowing light emission by current injection.
Impact of Research Achievements
■ Development of ultraviolet sources that use short wavelengths, such as highly condensed optical memory, ultraviolet microscopes and lithography.
■ Application to photoreaction processing, glass processing and medical ultraviolet lasers that uses strong light from chemical reactions are anticipated.
