Abstract
Extended long wavelength infrared detection with a miniband-type AlGaAs/GaAs superlattice structure is reported. The experimental response band of the detector is peaked near 14.5 μm in good agreement with the theoretical response, provided that electron-electron interactions are taken into account. The detector operates at a low bias voltage, which could lead to important advantages in application to IR focal plane arrays.Keywords
