Lead selenide (PbSe), or lead(II) selenide, a selenide of lead, is a semiconductor material. It forms cubic crystals of the NaCl structure; it has a direct bandgap of 0.27 eV at room temperature.

2022年10月28日 · PbSe-based thermoelectric materials exhibit promising ZT values at medium temperature, but its near-room-temperature thermoelectric properties are overlooked, thus restricting its average ZT...

2009年3月3日 · Lead selenide is a chemical compound of lead and selenium that can be found as the naturally occuring mineral clausthalite. It is a semiconductor and is used for manufacture of infrared detectors for thermal imaging.

2024年3月14日 · We demonstrate how removing lattice vacancies through a grid-design strategy switched PbSe from being useful as a medium-temperature power generator to a thermoelectric cooler.

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

In this paper, we report a systematic study of electronic structures and lattice dynamics of the lead chalcogenides PbX X=Te, Se, and S using first-principles density-functional-theory calculations and a direct force-constant method.
