Be2Mg1Os1
Be2Mg1Os1 is a semiconducting ternary compound of beryllium, magnesium, and osmium that is currently identified as a metastable phase.
About Be2Mg1Os1
Be2Mg1Os1 is a complex ternary inorganic compound composed of beryllium, magnesium, and osmium. It exhibits semiconducting electronic behavior, positioning it as an interesting subject for fundamental research into the interaction between light alkaline earth metals and heavy transition metals.
Despite its existence in multiple structural forms within computational databases, the compound is characterized as being thermodynamically above the hull. This suggests that it may be metastable or difficult to synthesize under standard laboratory conditions, requiring specific high-pressure or non-equilibrium processing routes.
Key Properties
Cross-validated computational properties for Be2Mg1Os1, aggregated across 2 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.
