Ag1Au1K2
Ag1Au1K2 is a semiconducting ternary intermetallic compound currently being explored in the context of perovskite-related material research.
About Ag1Au1K2
Ag1Au1K2 is a semiconducting material composed of silver, gold, and potassium. It is categorized within the broad research landscape of halide perovskite-related structures, where researchers investigate unique electronic configurations for potential optoelectronic applications.
Despite its inclusion in structural databases, this compound is considered thermodynamically unstable, as it sits above the stability hull. Its existence as a reported structure highlights the ongoing effort to map the complex phase space of ternary and quaternary metallic systems.
Key Properties
Cross-validated computational properties for Ag1Au1K2, aggregated across 2 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.
