About K2Mo2O7
K2Mo2O7 is a potassium-based molybdenum oxide that exists as a thermodynamically stable phase. Its electronic character is defined by a wide band gap, classifying it as an insulating material within the broader family of alkali metal molybdates.
Because it sits on the convex hull, this compound is highly stable, making it a reliable subject for structural studies. It is frequently investigated for its role in solid-state chemistry and its potential utility in specialized optical or catalytic applications.
Key Properties
Cross-validated computational properties for K2Mo2O7, aggregated across 4 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.
