FeCuSe2
semiconductor· FeCuSe2
FeCuSe2 is an iron-copper selenide semiconductor compound combining iron, copper, and selenium in a mixed-valence structure. This material belongs to the family of chalcogenide semiconductors and is primarily investigated in research contexts for photovoltaic and thermoelectric applications, where its tunable band gap and mixed-metal composition offer potential advantages over single-element or binary semiconductors. Its layered crystal structure and semiconductor properties make it a candidate for next-generation energy conversion devices, though industrial adoption remains limited compared to established semiconductors like silicon or cadmium telluride.
