Infrared detector and method of detecting one or more bands of infrared radiation

An infrared detector is provided. The infrared detector includes an absorption layer sensitive to radiation in only a short wavelength infrared spectral band, and a barrier layer coupled to the absorption layer. The barrier layer is fabricated from an alloy including aluminum and antimony, and at le...

More Information
Summary:An infrared detector is provided. The infrared detector includes an absorption layer sensitive to radiation in only a short wavelength infrared spectral band, and a barrier layer coupled to the absorption layer. The barrier layer is fabricated from an alloy including aluminum and antimony, and at least one of gallium or arsenic, and the composition of the alloy is selected such that valence bands of the absorption layer and the barrier layer substantially align.
