About Ba3Ho4O9
Ba3Ho4O9 is an insulating oxide compound composed of barium, holmium, and oxygen. Its electronic structure is characterized by a wide band gap, which is typical for stable ternary oxides of this nature. The material is considered thermodynamically near-hull, suggesting that it is a viable target for experimental synthesis and structural characterization.
Due to its unique composition, this compound serves as a subject of interest in solid-state chemistry. Its existence across multiple structural databases highlights its potential role in developing specialized ceramic materials or as a precursor for complex oxide systems where insulating properties are required.
Key Properties
Cross-validated computational properties for Ba3Ho4O9, 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.
