Interband cascade devices
Patent
·
OSTI ID:1568312
Photovoltaic (PV) and photodetector (PD) devices, comprising a plurality of interband cascade (IC) stages, wherein the IC stages comprise an absorption region with a type-I superlattice and/or a bulk semiconductor material having a band gap, the absorption region configured to absorb photons, an intraband transport region configured to act as a hole barrier, and an interband tunneling region configured to act as an electron barrier, wherein the absorption region, the intraband transport region, and the interband tunneling region are positioned such that electrons will flow from the absorption region to the intraband transport region to the interband tunneling region.
