MgOsY2
MgOsY2 is a semiconducting ternary compound consisting of magnesium, osmium, and yttrium that exists in a metastable state.
About MgOsY2
MgOsY2 is a complex ternary material composed of magnesium, osmium, and yttrium. As a semiconducting compound, it occupies a specialized niche in materials research where electronic properties are tuned by the interplay of its constituent elements.
Despite its existence in multiple structural configurations across various databases, the compound is characterized as being above the thermodynamic hull. This suggests that while it can be synthesized or modeled, it remains in a metastable state that requires specific conditions for stabilization.
Key Properties
Cross-validated computational properties for MgOsY2, 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.
