Li7OsO6
Li7OsO6 is a semiconducting lithium-osmium oxide that is considered a viable candidate for synthesis due to its favorable thermodynamic stability.
About Li7OsO6
Li7OsO6 is a complex lithium oxide characterized by its semiconducting electronic nature. As a material situated near the thermodynamic hull, it represents a promising candidate for experimental synthesis and structural investigation within the broader family of lithium-based oxides. Its unique arrangement of lithium, osmium, and oxygen atoms suggests distinct coordination environments that are of significant interest for fundamental solid-state chemistry studies. The compound is primarily studied for its potential role in developing high-performance electrode materials or specialized electrochemical components where precise electronic control is required. Its structural flexibility and the presence of transition metal centers make it a compelling subject for researchers exploring novel lithium-rich phases.
Key Properties
Cross-validated computational properties for Li7OsO6, 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.
