Lead Sulfide (PbS) and Lead Selenide (PbSe) detectors are both members of the lead-salt family of photoconductive infrared detectors, which are sensitive in the 1 – 5.5 micrometer range of the ...

In the long wavelength spectral region, photoconductive detectors (PC-MCT) are best suited for meeting low-noise requirements. At shorter wavelengths, photovoltaic devices (PV-MCT) are suitable ...

The photoconductive detector can be designed to have built-in gain. That is, the absorption of a photon can lead to the generation of many electrons in the resulting photocurrent, whereas a photodiode ...

Finally, a photoconductive detector was fabricated based on the HgSe/CsPbBr x I 3-x heterojunction. The objective of the study was to develop a feasible strategy for CQD-based heterojunction ...
