AgBrHgS
AgBrHgS is a thermodynamically stable semiconducting quaternary compound composed of silver, bromine, mercury, and sulfur.
About AgBrHgS
AgBrHgS is a complex quaternary inorganic compound that exhibits semiconducting electronic behavior. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement of silver, bromine, mercury, and sulfur atoms.
This material is of significant interest to researchers investigating multi-component chalcogenide-halide systems. Its stability suggests potential for specialized applications in optoelectronics or advanced sensing technologies where precise control over electronic properties is required.
Key Properties
Cross-validated computational properties for AgBrHgS, 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.
