Th2 P2 Se2

Th₂P₂Se₂ is a ternary semiconductor compound combining thorium, phosphorus, and selenium elements, belonging to the class of rare-earth and actinide-based semiconducting materials. This is primarily a research-phase compound studied for its electronic and optoelectronic properties rather than an established commercial material. The thorium-based semiconductor family is of interest in nuclear-related applications, specialized radiation detection, and high-temperature electronics research, though practical deployment remains limited due to thorium's regulatory status, radioactivity concerns, and the material's relative immaturity compared to conventional semiconductor platforms.
