DIAMOND ULTRAVIOLET LIGHT-EMITTING DEVICE

摘要

A small, simple current-injection diamond ultraviolet light-emitting device comprising a high-quality vapor phase process diamond (1), a surface conductive layer (2) provided on the surface of the diamond, and electrodes (4, 5) provided on the surface conductive layer. The device is a free-exciton recombination emission diamond ultraviolet light-emitting device comprising a vapor phase synthesis diamond crystal where free-exciton recombination emission (235 nm) caused by current injection is dominant.
