Nb5VFe2Se20
metal· JVASP-145829· Nb5VFe2Se20
Nb5VFe2Se20 is a transition metal selenide compound combining niobium, vanadium, and iron with selenium, representing an emerging class of polymetallic chalcogenides. This material is primarily of research and developmental interest, studied for potential applications in thermoelectric energy conversion, where the complex crystal structure and electronic properties of multi-metal selenides show promise for improving thermal-to-electrical efficiency. The material's notable feature is its layered structure characteristic of selenide compounds, which can exhibit interesting electronic and phononic properties that distinguish it from conventional metallic or single-component semiconductor materials.
