About Fe3Ge2
Fe3Ge2 is a metallic iron-germanium compound that exists in a metastable state. Its electronic character is defined by its metallic nature, lacking a traditional band gap, which positions it as a subject of interest for fundamental studies in transition metal-metalloid systems.
Due to its complex structural landscape, this material has been documented across multiple databases with numerous reported configurations. Its metastability suggests a delicate balance of formation conditions, making it a key candidate for researchers investigating phase stability in iron-based intermetallics.
Key Properties
Cross-validated computational properties for Fe3Ge2, aggregated across 6 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
