Abstract : A multispectral photovoltaic infrared detector comprises a plurality of layers of single-crystal, lead/alloy semiconductors on a single-crystal substrate of, e.g., barium fluoride, wherein each layer, except the one covering the substrate, partially covers the preceeding layer; a layered concentration of oxides between the layers to provide a positive-charge barrier to the minority-charge-carriers in the layers; a P-N junction in each layer in the uncovered portion thereof; an electrical contact connected to each P-N junction; and an electrical contact on the P-type portion of least one semiconductor layer.
