About CrFe
CrFe is a metallic binary compound composed of chromium and iron. As a metastable phase, it represents a unique configuration of these transition metals that is frequently studied in the context of alloy physics and phase stability investigations.
Because of its metallic nature and the prevalence of its constituent elements, this compound is a subject of extensive structural analysis. It serves as a critical reference point for understanding how iron and chromium interact at the atomic level across a wide array of experimental and theoretical structural models.
Key Properties
Cross-validated computational properties for CrFe, aggregated across 5 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.
