Heterostructure Band Engineering of Type-II InAs/GaSb Superlattice ...

and lineup. Nature of unipolar current blocking layer was investigated and dark current reduction mechanisms were
discussed. The peak D* for the PbIbN design is 2×10 10 (cm-√Hz)/W at -0.5 V. The measured value of responsivity at this
bias is 3.4 A/W and QE of 35% for 10 µm wavelength.
