Abstract
Techniques are disclosed for facilitating detection of electromagnetic radiation using superlattice-based detector systems and methods. In one example, an infrared detector includes a first superlattice structure including first periods. Each of the first periods includes a first sub-layer and a second sub-layer adjacent to the first sub-layer. The first and second sub-layers include first and second semiconductor materials. The infrared detector further includes a second superlattice structure disposed on the first superlattice structure. The second superlattice structure includes second periods. Each of the second periods includes a third sub-layer and a fourth sub-layer adjacent to the third sub-layer. The third-sub-layer includes a third semiconductor material. The fourth sub-layer includes a fourth semiconductor material. A p-n junction is formed at an interface within the second superlattice structure or at an interface between the first and second superlattice structures.
