BaTe2
Barium ditelluride is a thermodynamically stable semiconducting compound formed from barium and tellurium.
About BaTe2
Barium ditelluride is a binary inorganic compound composed of barium and tellurium. It is characterized as a semiconducting material that maintains thermodynamic stability, sitting directly on the convex hull of its constituent elements. Its structural versatility is evidenced by the extensive number of reported configurations found across major materials databases.
This compound represents a significant subject of study for researchers investigating chalcogenide-based semiconductors. Its stable nature and electronic profile make it a compelling candidate for exploring fundamental solid-state chemistry and potential applications in electronic or optoelectronic device development.
Key Properties
Cross-validated computational properties for BaTe2, 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.
