Results are reported on infrared photodiodes which have been designed to minimize the dark diffusion currents for operating temperatures above 200 K in the MWIR (3–5 µm) waveband. It is shown that by adjusting the doping and composition profiles,

Auger suppression reduces the leakage current in uncooled CdHgTe diodes to the point where the shot noise limited D* is significantly higher than for other uncooled detectors. However, Auger-suppressed diodes exhibit high levels of 1/f noise and so a

By taking advantage of Auger suppression techniques, the leakage currents of room temperature infrared detectors operating in the LWIR band can be greatly reduced. At present, these detectors suffer from large 1/f noise and hence the improvement in t
