Li1Os2Ta1
Li1Os2Ta1 is a semiconducting ternary compound containing lithium, osmium, and tantalum that exhibits complex structural characteristics.
About Li1Os2Ta1
Li1Os2Ta1 is a complex ternary compound composed of lithium, osmium, and tantalum. Its electronic character is defined as semiconducting, marking it as an interesting subject for fundamental research into the interplay between transition metals and alkali elements.
Despite its structural diversity, with numerous reported configurations, the compound is characterized as being above the thermodynamic hull. This suggests that it may be metastable under standard conditions, requiring specific synthetic pathways to stabilize its crystalline framework.
Key Properties
Cross-validated computational properties for Li1Os2Ta1, 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.
