LaV3O9
LaV3O9 is a metastable, semiconducting lanthanum vanadium oxide used primarily in fundamental materials science research.
About LaV3O9
LaV3O9 is a complex oxide composed of lanthanum, vanadium, and oxygen. As a semiconducting material, it exhibits electronic behavior that distinguishes it from simple binary oxides, making it a subject of interest for researchers investigating transition metal oxide systems. The compound is characterized as metastable, indicating that its synthesis and preservation require specific conditions to maintain its structural integrity. Its existence across multiple reported structures highlights the structural diversity inherent in lanthanum-based vanadates.
Key Properties
Cross-validated computational properties for LaV3O9, 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.
