Abstract:
1. A III-nitride optoelectronic device structure comprising: a dopant-containing doped III-nitride layer; an active region; and a barrier layer disposed between the doped III-nitride layer and the active region, said barrier layer being formed of a material comprising ALGaN having at least 50% Al, based on the total amount of Al and Ga therein; characterized by any of the following: (a) the optoelectronic device structure comprises any of a UV LED and a UV laser diode; and (b) any of the barrier layer and a portion of the doped III-nitride layer contains the dopant in a concentration that varies with depth, with a dopant concentration having a local maximum along an interface between the barrier layer and the doped III-nitride layer.
