Th2 Sb2 Se2
semiconductor· Th2 Sb2 Se2
Th₂Sb₂Se₂ is a ternary chalcogenide semiconductor compound combining thorium, antimony, and selenium. This is a research-phase material primarily studied for its potential in thermoelectric and optoelectronic applications, as part of the broader family of heavy-metal chalcogenides that can exhibit favorable band structures and phonon-scattering characteristics. The material remains largely experimental; potential advantages over conventional semiconductors would depend on optimizing its thermal conductivity, carrier mobility, and stability for practical device integration.
