· Sr2 Fe2 Se2 O1 F2

Sr₂Fe₂Se₂O₁F₂ is an experimental mixed-anion semiconductor combining strontium, iron, selenium, oxygen, and fluorine in a layered structure. This compound belongs to an emerging class of oxyselenide-fluoride semiconductors under active research for photovoltaic and optoelectronic applications, where the mixed-anion approach offers tunable bandgaps and enhanced charge transport compared to single-anion analogs. The material remains primarily in development stages; its adoption depends on demonstrating stability, scalability, and performance advantages in device contexts where conventional semiconductors (silicon, perovskites) face limitations.
