Sn0.13Pb0.87Se1

Sn₀.₁₃Pb₀.₈₇Se is a lead-tin selenide compound belonging to the IV-VI narrow-bandgap semiconductor family, typically investigated for narrow-gap optoelectronic and thermoelectric applications. This material composition sits within the PbSe-SnSe solid solution system and is primarily of research interest rather than established industrial production; it is studied for infrared detectors, thermal imaging sensors, and potential thermoelectric energy conversion where narrow bandgap semiconductors offer sensitivity in the mid-to-far infrared spectrum. The lead-rich composition makes it notable for applications requiring room-temperature or moderately cooled operation in the 3–14 μm wavelength range, though researchers continue to optimize doping and composition to improve performance relative to pure PbSe or commercial HgCdTe alternatives.
