Se2 Rb1 Ho1

Rb2SeHo is an experimental ternary compound combining rubidium, selenium, and holmium in a semiconducting phase. This material belongs to the rare-earth chalcogenide family and is primarily of research interest for investigating electronic and thermal properties in systems combining alkali metals with lanthanide elements. Applications remain largely exploratory, with potential directions in thermoelectric devices, photonic materials, or high-temperature semiconductor research where the rare-earth dopant can introduce unique electronic states.
