摘要： An electromagnetic radiation detector pixel includes a set of epitaxial layers and a lens. The set of epitaxial layers defines an electromagnetic radiation absorber. The lens is directly bonded to the set of epitaxial layers.

摘要： An electromagnetic radiation detector includes a PN junction between two group III-V semiconductor materials. The PN junction is defined by in-situ doping of the layers to improve the quality of the junction and the performance of the electromagnetic radiation detector.

摘要： A photodetector may include a substrate having a larger lattice constant than an absorber layer. A reverse graded set of buffer layers may provide lattice matching between the substrate and the absorber layer. The substrate may comprise indium arsenide (InAs). The absorber layer may comprise one of indium gallium arsenide (InxGa1-xAs), indium arsenide phosphide (InAsxP1-x), and indium aluminum arsenide (InxAl1-xAs).
