Highly efficient III-nitride-based top emission type light emitting device having large area and high capacity
Abstract:
A nitride-based top emission type light emitting device and a method of manufacturing the same, the light emitting device including an n-nitride-based cladding layer, a p-nitride-based cladding layer, a nitride-based active layer, and a multiple p-ohmic contact layer. The multiple p-ohmic contact layer includes at least one pair of an ohmic modification layer and a transparent conducting layer. The ohmic modification layer includes a poly-crystal nitride layer or an amorphous nitride layer including nitrogen (N) combined with at least one of aluminum (Al), indium (In) or gallium (Ga). The ohmic modification layer is prepared in the form of a droplet or a thin film. Pores or dots are formed on the poly-crystal nitride layer or the amorphous nitride layer so as to provide the multiple p-ohmic contact layer with a photonic crystal effect.
