Abstract:
A radiation detector for detecting electromagnetic radiation at a plurality of spectral bands, comprising:a multi-layered semiconductor structure comprising a plurality of layers, wherein each of the layers of the multi-layered semiconductor structure comprises a first conductivity type;a first planar diode deposited in a first color layer of the multi-layered semiconductor structure, the first planar diode intersecting only a portion of a planar surface area of the first color layer, the first color layer having a first band gap and the first planar diode having a second conductivity type; andan additional planar diode deposited in an additional color layer of the multi-layered semiconductor structure, the additional color layer having an additional band gap and the additional planar diode having the second conductivity type, the first band gap being greater than the second band gap and the additional planar diode intersecting only a portion of a planar surface area of the additional color layer.
