AgO2
AgO2 is a metallic, metastable silver oxide known for its structural complexity and diverse range of reported configurations.
About AgO2
AgO2 is a metallic silver-oxygen compound characterized by its complex structural landscape. With hundreds of reported configurations across various databases, it represents a highly studied system in the exploration of silver-based oxides. Its metallic nature distinguishes it from many typical insulating binary oxides, making it a subject of interest for fundamental materials research.
As a compound that resides above the thermodynamic hull, AgO2 is generally considered a metastable phase. Its existence is often tied to specific synthesis conditions that allow for the stabilization of its unique atomic arrangements, which are critical for understanding the broader chemical behavior of silver oxides under non-equilibrium conditions.
Key Properties
Cross-validated computational properties for AgO2, 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.
