Mid-wave infrared technology is dominated by HgCdTe ternary alloy. As of now, InAs/GaSb type-II superlattice has shown the theoretical potential to compete with HgCdTe. Type-II superlattice InAs/GaSb technology is under development, where proper dete

Most of the HgCdTe infrared detectors are fabricated by mesa geometry using a wet chemical or plasma etching techniques. The mesa definition etch process induces undesirable changes in HgCdTe surface properties. In narrow bandgap materials these surf
