About Fe3Ge
Fe3Ge is a stable intermetallic compound composed of iron and germanium. As a metallic material, it exhibits characteristic conductive properties and maintains a high degree of structural integrity, sitting directly on the thermodynamic convex hull. Its presence across numerous reported structures highlights its significance in materials science research. This compound is frequently studied for its role in magnetic and electronic systems, where the interplay between iron and germanium atoms dictates its physical behavior. Its stability makes it a reliable subject for investigating phase transitions and alloying effects in metal-rich systems.
Key Properties
Cross-validated computational properties for Fe3Ge, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
