The authors report on investigation of type-II InAs/GaSb and InAs/InxGa1−xSb strained layer superlattices SLSs for long-wave infrared detection. Growth conditions were optimized to obtain nearly lattice matched a /a 0.03% 13 ML InAs/7 ML GaSb SLS nBn detector structure with cutoff wavelength of 8.5 m 77 K . Dark current density was equal to 3.2 10−4 A /cm2 Vb =+50 mV, 77 K for this detector str...
The nonlinearity characteristics of a commercially available thin-film photoconductive PbS detector were experimentally investigated in the infrared using the National Physical Laboratory detector linearity characterization facility. The deviation from linearity of this detector was shown to be significant even for relatively low values of radiant power incident on the active area of the detect...
Seebeck effect is one of the desirable pathways for developing advanced room-temperature (RT) broadband photothermoelectric (PTE) detectors, which are important infrared spectroscopy applications. However, achieving high performance PTE detectors utilizing materials with coefficient remains a great challenge and further improvements highly desired. Herein, we introduce layered material SnSe up ...
