· JVASP-40773· VFeSe

VFeSe is an intermetallic compound combining vanadium, iron, and selenium, belonging to the family of transition metal selenides. This material is primarily of research interest for its potential in thermoelectric and magnetoelectric applications, where the combination of metallic iron and vanadium with semiconducting selenium offers tunable electronic and thermal transport properties. Limited industrial deployment exists; VFeSe is explored in laboratory settings for next-generation energy conversion devices and as a model compound for understanding electronic behavior in mixed-valence metal selenide systems.
