Abstract
An improved heterostructure for an optoelectronic device is provided. The heterostructure includes an active region, an electron blocking layer, and a p-type contact layer. The electron blocking layer is located between the active region and the p-type contact layer. In an embodiment, the electron blocking layer can include a plurality of sublayers that vary in composition.
