· Ba8Hg4S5Se7

Ba8Hg4S5Se7 is a mixed-chalcogenide semiconductor compound containing barium, mercury, sulfur, and selenium elements. This material belongs to the family of complex sulfide-selenide semiconductors and appears to be primarily of research interest rather than established in mainstream industrial production. Materials in this chemical family are investigated for potential applications in thermoelectric energy conversion, optoelectronic devices, and radiation detection, where the combination of heavy elements and tunable band gaps can offer advantages over conventional binary semiconductors.
