Al2FeSi
Al2FeSi is a stable, semiconducting intermetallic compound composed of aluminum, iron, and silicon.
About Al2FeSi
Al2FeSi is a distinct intermetallic compound characterized by its semiconducting electronic nature. As a thermodynamically stable phase residing on the convex hull, it represents a robust structural arrangement of aluminum, iron, and silicon atoms that maintains its integrity under standard conditions.
This material is of significant interest for researchers investigating complex ternary systems. Its stability and electronic properties suggest potential utility in specialized electronic or structural applications where precise control over material composition and behavior is required.
Key Properties
Cross-validated computational properties for Al2FeSi, aggregated across 3 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.
