Al3Os2
Al3Os2 is a metallic intermetallic compound formed from aluminum and osmium that exhibits significant structural stability.
About Al3Os2
Al3Os2 is a metallic intermetallic compound composed of aluminum and osmium. Its electronic character is defined by its metallic nature, lacking a band gap, which influences its potential for specialized conductive applications. The material is recognized for being near the thermodynamic hull, suggesting it is a stable phase that is likely synthesizable under controlled experimental conditions.
With extensive data available across multiple structural databases, this compound represents a well-documented system for researchers studying binary aluminides. Its structural complexity and stability profile make it an interesting candidate for investigations into transition metal-aluminum phase behavior and alloy development.
Key Properties
Cross-validated computational properties for Al3Os2, 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.
