K2Fe2SeS3
metal· JVASP-104954· K2Fe2SeS3
K2Fe2SeS3 is a mixed-metal chalcogenide compound containing potassium, iron, selenium, and sulfur, belonging to the family of layered metal sulfides and selenides. This is primarily a research-stage material studied for its potential in semiconductor and photoelectric applications, rather than an established engineering material in widespread industrial use. The compound's mixed chalcogenide structure makes it of interest for exploring electronic properties in materials science research, though practical engineering applications remain under investigation.
