ScTlO2
ScTlO2 is a semiconducting ternary oxide containing scandium and thallium that is currently studied for its structural diversity and metastable thermodynamic state.
About ScTlO2
ScTlO2 is a complex ternary oxide composed of scandium, thallium, and oxygen. As a semiconducting material, it represents a unique combination of a transition metal and a heavy post-transition metal, offering an intriguing electronic structure for fundamental materials research.
Due to its position above the thermodynamic hull, this compound is considered metastable, which makes it a subject of significant interest for synthetic chemists and materials scientists studying phase stability. Its existence across multiple reported structures highlights the complexity of its potential bonding environments.
Key Properties
Cross-validated computational properties for ScTlO2, 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.
