 How does a PbS photoconductive detector work? by Shimadzu Scientific Instruments

Manufacturer’s technical FAQ. The operating-principle paragraphs explain excitation across the band gap, electron/hole generation and a light-dependent resistance read through an external circuit. The temperature paragraph describes changes in spectral sensitivity, response speed and dark resistance. The displayed heading is How does a PbS photoconductive detector work? No individual byline or publication date is asserted.
