Abstract
A layered structure used for detecting incident light includes a substrate having a surface with a high Miller index crystal orientation and a superlattice structure formed over the substrate at the surface. The superlattice structure is aligned to the high Miller index crystal orientation and exhibits a red-shifted long wave infrared response range based on the crystal orientation as compared to a superlattice structure formed over a substrate at a surface with a (100) crystal orientation.
