V2 Fe1 Se4

V₂Fe₁Se₄ is a layered transition metal selenide compound combining vanadium and iron with selenium, belonging to the family of chalcogenide semiconductors. This material is primarily investigated in research contexts for its potential as a thermoelectric material and in energy conversion applications, where its layered structure and mixed-metal composition may offer advantages in phonon scattering and charge transport. The vanadium-iron selenide system remains largely experimental, with engineering interest centered on next-generation thermoelectric devices and potentially on catalytic or photovoltaic applications where mixed transition metals provide tunable electronic properties.
