Ba2TeO
Ba2TeO is a thermodynamically stable, semiconducting ternary oxide compound.
About Ba2TeO
Ba2TeO is a thermodynamically stable inorganic compound that exists firmly on the convex hull, indicating robust structural integrity. As a semiconducting material, it occupies a specific niche in solid-state chemistry where its unique arrangement of barium, tellurium, and oxygen atoms dictates its electronic behavior.
This compound is characterized by significant structural diversity, with multiple documented configurations across materials databases. Its stability and semiconducting nature make it a subject of interest for researchers investigating complex ternary oxides and their potential for advanced electronic applications.
Key Properties
Cross-validated computational properties for Ba2TeO, 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.
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.
