Os2TaY
Os2TaY is a semiconducting ternary compound containing osmium, tantalum, and yttrium that is currently categorized as a metastable phase.
About Os2TaY
Os2TaY is a complex ternary compound composed of osmium, tantalum, and yttrium. As a semiconducting material, it represents a unique combination of transition metals that has been identified across multiple structural configurations in computational databases. Its electronic character suggests potential for specialized solid-state applications where specific band structures are required.
Despite its presence in structural databases, the compound is characterized as being above the thermodynamic hull, suggesting it is likely unstable under ambient conditions. This status highlights the ongoing research interest in identifying metastable phases that could potentially be stabilized through advanced synthesis techniques or thin-film growth methods.
Key Properties
Cross-validated computational properties for Os2TaY, 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.
