AgAuO3
AgAuO3 is a metastable semiconducting oxide containing both silver and gold that is primarily studied for its unique electronic characteristics.
About AgAuO3
AgAuO3 is a ternary oxide compound featuring both silver and gold cations. As a semiconducting material, it exhibits electronic properties that bridge the gap between traditional metallic oxides and more complex transition metal systems, making it a subject of interest for fundamental materials science studies.
Due to its metastable nature, this compound requires specific synthesis conditions to stabilize its structure. Its existence in multiple reported configurations across various databases highlights the complexity of its phase space and the ongoing efforts to characterize its potential utility in specialized electronic applications.
Key Properties
Cross-validated computational properties for AgAuO3, 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.
