About barium germanate
Barium germanate is a stable inorganic compound composed of barium, germanium, and oxygen. As a wide-band-gap insulator, it exhibits robust electronic characteristics that make it a subject of significant interest for fundamental materials research.
Its thermodynamic stability on the convex hull underscores its structural integrity, which is supported by a diverse array of reported experimental and computational crystal structures. This stability facilitates its potential integration into specialized electronic and optical device architectures.
Key Properties
Cross-validated computational properties for barium germanate, 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.
