Tl3VO4
Tl3VO4 is a stable, semiconducting thallium vanadate compound used in fundamental solid-state materials research.
About Tl3VO4
Tl3VO4 is a distinct ternary oxide composed of thallium, vanadium, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions.
This compound exhibits semiconducting electronic characteristics, making it an interesting candidate for studies involving electronic transport and solid-state chemistry. Its existence across multiple reported structures highlights its significance within the broader landscape of complex metal vanadates.
Key Properties
Cross-validated computational properties for Tl3VO4, 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.
