ELECTRICALLY PUMPED OPTOELECTRONIC SEMICONDUCTOR CHIP
摘要:
An electrically pumped optoelectronic semiconductor chip includes at least two radiation-active quantum wells comprising InGaN or consisting thereof. The optoelectronic semiconductor chip includes at least two cover layers which include AlGaN or consist thereof. Each of the cover layers is assigned to precisely one of the radiation-active quantum wells. The cover layers are each located on a p-side of the associated radiation-active quantum well. The distance between the radiation-active quantum well and the associated cover layer is at most 1.5 nm.
