In this paper, the relation between the photoluminescence (PL) intensity and the PL peak wavelength was studied. A linear decrease of the PL intensity with increasing cut-off wavelength of long wavelength infrared CBIRDs was observed at 77 K and the

Quantum Sensing and Nanophotonic Devices XII.
In this work we investigate the high temperature performance of mid-wavelength infrared InAsSb-AlAsSb nBn detectors with cut-off wavelengths near 4.5μm. The quantum efficiency of these devices is 35% without antireflection coatings and does not chan

A sample cell, capable of supporting standard 13 mm diameter pressed pellets, and suitable for mounting in a commercial cryostat, has been constructed of Invar, and fitted with two thermocouple sensors for operating in the range 4.2 < T < 300 K. The
