About barium tellurite
Barium tellurite is a thermodynamically stable inorganic compound characterized by its insulating electronic nature. As a member of the tellurite family, it exhibits significant structural versatility, supported by multiple documented crystalline phases that highlight its robust chemical identity.
This material is of interest for its dielectric and optical properties, which are typical of wide-gap oxides containing heavy metal cations. Its stability on the convex hull suggests it is a well-defined phase suitable for further investigation in specialized electronic and ceramic applications.
Key Properties
Cross-validated computational properties for barium tellurite, 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.
