Latest Patents

Ohono holds a patent for a transparent electrode designed for use in gallium nitride-based compound semiconductor light-emitting devices. This innovative electrode operates at an emission wavelength of 440 nm or less. The design includes a metal layer adjacent to a p-type semiconductor layer and a current diffusion layer on top of the metal layer. Notably, the transparent electrode contains virtually no gold throughout its entirety. The metal layer is composed of one element selected from platinum, iridium, ruthenium, or rhodium as a primary component. The current diffusion layer also contains one of these elements, unless both layers share the same composition. This technology enables the creation of white light-emitting devices, white light-emitting lamps, and lighting fixtures utilizing these lamps.
