AlCr2W
AlCr2W is a semiconducting ternary intermetallic compound that exists in a metastable state.
About AlCr2W
AlCr2W is a ternary compound composed of aluminum, chromium, and tungsten. As a semiconducting material, it exhibits unique electronic properties that distinguish it from typical metallic alloys, though its thermodynamic profile suggests it exists in a metastable state above the ground state hull.
The material has been subject to significant structural investigation, with multiple distinct configurations documented across various databases. This interest highlights its role as a subject of fundamental research into complex ternary systems where electronic behavior is influenced by the interplay of its constituent transition metals and aluminum.
Key Properties
Cross-validated computational properties for AlCr2W, 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.
