YAgO2 is a stable, semiconducting ternary oxide of yttrium and silver used in materials research.
About YAgO2
YAgO2 is a distinct ternary oxide composed of yttrium, silver, and oxygen. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. Its semiconducting electronic character makes it an intriguing candidate for electronic and optoelectronic material studies.
The compound is characterized by a notable degree of data availability, with multiple reported structures across major materials databases. This structural diversity highlights the complexity of its lattice configurations and underscores its importance as a subject for computational and experimental investigation in the search for functional oxides.
Key Properties
Cross-validated computational properties for YAgO2, 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.
