· K2Hg3S2.69Se1.31

K2Hg3S2.69Se1.31 is an experimental mixed-chalcogenide semiconductor compound combining potassium, mercury, sulfur, and selenium in a quaternary phase. This material belongs to the family of mercury-based chalcogenides, which are primarily investigated in research settings for their unique electronic and optical properties arising from the partial substitution of sulfur with selenium. While not yet widely deployed in commercial applications, materials in this class are of interest for narrow-bandgap semiconductor devices and optoelectronic research where the tunable composition allows control of electronic properties.
