Li2V2SnO6
Li2V2SnO6 is a metastable semiconducting oxide composed of lithium, vanadium, tin, and oxygen.
About Li2V2SnO6
Li2V2SnO6 is a complex oxide containing lithium, vanadium, tin, and oxygen. As a semiconducting material, it exhibits electronic properties that make it a subject of interest for researchers investigating new functional inorganic compounds. Its status as a metastable phase suggests unique structural configurations that can be accessed under specific synthesis conditions. Because it is a relatively niche compound, it represents an opportunity to explore how transition metal and main group elements interact within a crystal lattice to influence charge transport. The ongoing study of this material across multiple databases highlights its importance in the broader effort to map the landscape of complex oxides.
Key Properties
Cross-validated computational properties for Li2V2SnO6, 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.
