· JVASP-152643· SiPtSe

SiPtSe is an intermetallic compound combining silicon, platinum, and selenium—a ternary metal system that blends the properties of a refractory metal (platinum) with semiconducting or semi-metallic character from silicon and selenium. This material is primarily of research interest rather than established in high-volume production, with applications explored in thermoelectric energy conversion, where the combination of metallic and chalcogenide phases offers potential for tuning thermal and electrical transport properties.
