This paper reports progress with work aimed at using HgCdTe detector arrays at temperatures above 200 K where cooling is possible with thermo-electric coolers. Both theoretical analysis and calculations based on the detector dark currents indicate th

The spectral properties of InSb/AlxIn1−xSb quantum-well light-emitting diodes have been investigated at T = 15K in a magnetic field of approximately 250mT, applied by mounting the diodes inside a toroidal permanent magnet. In all cases, the low ene

We have previously discussed the potential of using a Hg1-xCdxTe source as a reference plane for the non-uniformity correction of thermal imagers and which is being developed as an option for the UK 3 rd generation, high performance thermal imaging p

Negative luminescent (NL) devices, which to an IR observer can appear colder than they actually are, have a wide range of possible applications, including use as modulated IR sources in gas sensing systems and as thermal radiation shields in IR camer

Dual-waveband, Focal Plane Arrays (FPAs) based on Hg1-xCdxTe multi-layer structures have previously been produced by the Molecular Beam Epitaxy (MBE) growth technique. It is shown that the multi-layer structures required for dual-waveband devices can

We have investigated the room-temperature electroluminescent properties of InSb/AlxIn1-xSb quantum-well light-emitting diodes. The maximum emission from diodes containing quantum wells occurred at significantly higher energies than the band gap of In

We have investigated the negative luminescent properties of a device fabricated from metalorganic vapor phase epitaxy grown HgCdTe on a Si substrate. The peak emission was at 7.2μm, and the intrinsic Auger processes were found to be very well suppre
