Abstract
An efficient light emitting diode is disclosed wherein the spatial distribution of emitted radiation is highly uniform. In accordance with the present invention, a transparent electrode is used to couple current to the light emitting diode junction in a manner that minimizes the resistance at the interface between the transparent electrode and semiconductor diode material. Specifically, it has been found that the interface resistance is significantly reduced, and device efficiency thus increased, by forming a thin metal-based layer at such interface and/or by annealing the transparent electrode after formation on the device.
