· Na0.5Ge1Pb1.75S4

Na0.5Ge1Pb1.75S4 is a mixed-metal chalcogenide semiconductor compound containing sodium, germanium, lead, and sulfur. This is a research-phase material under investigation for mid-infrared photonics and thermoelectric applications, belonging to the broader family of lead-chalcogenide semiconductors known for tunable bandgaps and strong light-matter interactions in the infrared region. The sodium doping and specific stoichiometry are designed to optimize carrier concentration and phonon scattering for either enhanced IR detection/emission or improved thermoelectric efficiency compared to undoped binary lead sulfide or lead selenide systems.
