Abstract
A nitride light-emitting diode includes a substrate, an n-type nitride layer, a light-emitting layer, a p-type nitride layer, a p+ layer, an AlInN layer, an n+ layer, and an ITO transparent electrode. A tunneling structure with an AlInN intermediate layer is adopted as the contact layer, which generates polarization charges at the tunneling junction interface and maintains effective width of the depletion region, thereby increasing tunneling probability of holes and reducing contact resistances.
