About AlFe2Ta
AlFe2Ta is a thermodynamically stable intermetallic compound that occupies a position on the convex hull, indicating robust structural integrity under standard conditions. As a semiconducting material, it represents a specialized electronic configuration that distinguishes it from typical metallic alloys composed of aluminum, iron, and tantalum.
Its existence across multiple structural databases highlights its significance in materials science research. This compound is primarily utilized in fundamental studies aimed at understanding the interplay between transition metals and light elements in complex crystalline lattices.
Key Properties
Cross-validated computational properties for AlFe2Ta, 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.
