Be2CuOs
Be2CuOs is a semiconducting ternary compound containing beryllium, copper, and osmium that is currently considered thermodynamically unstable.
About Be2CuOs
Be2CuOs is a complex ternary compound composed of beryllium, copper, and osmium. It exhibits semiconducting electronic behavior, positioning it as a subject of interest for researchers investigating the interplay between light elements and heavy transition metals in solid-state chemistry.
Despite being identified across multiple structural databases, the compound is characterized as being above the thermodynamic hull. This suggests that it may be metastable or difficult to synthesize in pure form, requiring specific conditions to stabilize its crystalline arrangement.
Key Properties
Cross-validated computational properties for Be2CuOs, 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.
