· ThSO

ThSO is a rare-earth sulfide semiconductor compound containing thorium and sulfur, belonging to the family of chalcogenide semiconductors. While primarily of research interest rather than established commercial use, ThSO represents an experimental material being investigated for potential optoelectronic and photovoltaic applications where rare-earth compounds offer tunable band gaps and unique electronic properties. The thorium-based composition distinguishes it from more common cadmium or lead chalcogenides, making it relevant to researchers exploring alternative semiconductor platforms with different carrier dynamics and radiation tolerance characteristics.
