ABSTRACT:
An improved light emitting device is provided. In a first embodiment, the light emitting device comprises: a first conductive layer having a first conductivity type; a light emitting material, the light emitting material disposed above the first conductive layer and in electrical communication therewith; a current aperture region, the current aperture region comprising at least one layer of oxidizable material, the layer of oxidizable material having a first region which is non-oxidized surrounded by a second region which is oxidized in order to form a current aperture in the oxidizable material, the current aperture region further comprising a third region being non-oxidized and at least adjacent to the second region, the current aperture region disposed above the light emitting material and in electrical communication therewith; a second conductive layer having a second conductivity type, the second conductive layer being disposed above the current aperture region and in electrical communication therewith; at least one electrically conductive channel for providing electrical communication to the light emitting material, the channel extending through the third region of the oxidizable material. Additionally, a method for constructing the light emitting device is also provided.
