· Ho2GeS5

Ho2GeS5 is a ternary semiconductor compound combining holmium, germanium, and sulfur, belonging to the rare-earth chalcogenide family. This is a research-phase material studied primarily for its potential in infrared optics, thermoelectric energy conversion, and solid-state electronic devices where rare-earth-doped semiconductors offer unique optical and thermal properties. Materials in this compound class are of interest to researchers exploring alternatives to more common semiconductors for niche applications requiring specific bandgap, luminescence, or thermoelectric characteristics.
