ThOS

ThOS (thorium oxide sulfide) is an experimental semiconductor compound combining thorium, oxygen, and sulfur elements, investigated primarily in materials research for its potential electronic and optoelectronic properties. While not yet commercially established, this material belongs to the family of mixed-anion semiconductors being explored for next-generation photovoltaics, photodetectors, and radiation-resistant electronics where thorium-based compounds offer unique band structure advantages. The novelty and limited industrial deployment mean ThOS remains a research-stage material; engineers would consider it only in specialized applications requiring thorium's nuclear or radiation-shielding properties coupled with semiconductor functionality.
