  • Mobility engineered electroluminescent devices
    Patent number: 8026512
    Abstract: An electroluminescent (EL) device, including a semiconductor structure, a first electrode, and a second electrode. The semiconductor structure includes: a first higher mobility semiconductor layer having a first mobility; a second higher mobility semiconductor layer having a second mobility; and a lower mobility semiconductor layer formed between the first higher mobility semiconductor layer and the higher mobility second semiconductor layer. The lower mobility semiconductor layer has a third mobility that is less than the first mobility and the second mobility. The semiconductor structure includes EL semiconducting material in the first higher mobility semiconductor layer, the second higher mobility semiconductor layer, and/or the lower mobility semiconductor layer. The first electrode is coupled to the first higher mobility semiconductor layer of the semiconductor structure. The second electrode is coupled to the second higher mobility semiconductor layer of the semiconductor structure.
