TbO3
TbO3 is a semiconducting oxide of terbium that exists as a metastable phase of interest in fundamental materials science research.
About TbO3
TbO3 is a semiconducting oxide composed of terbium and oxygen. As a member of the rare-earth oxide family, it represents a complex coordination environment that has been the subject of multiple structural investigations across various databases. Its electronic properties suggest potential utility in specialized semiconductor research where unique lanthanide-based behaviors are required.
Due to its thermodynamic profile, this compound is situated above the stability hull, suggesting it is a metastable or unstable phase under standard conditions. This makes TbO3 a fascinating subject for high-pressure synthesis or thin-film deposition studies, where non-equilibrium conditions may allow for the stabilization of its specific crystalline lattice.
Key Properties
Cross-validated computational properties for TbO3, 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.

How It Compares
As a member of the broader terbium-oxygen system, TbO3 occupies a unique space compared to more common, highly stable terbium oxides. While other oxides in the lanthanide series often form highly predictable, thermodynamically favored structures, TbO3 stands out as a challenging, less conventional phase that requires specific synthetic pathways to access.
