AlAgS2
AlAgS2 is a thermodynamically stable semiconducting ternary sulfide compound.
About AlAgS2
AlAgS2 is a distinct ternary sulfide that maintains thermodynamic stability within its structural landscape. As a semiconducting material, it represents a stable configuration of silver, aluminum, and sulfur atoms that has been characterized across multiple structural databases.
Its existence on the convex hull underscores its robustness as a material phase. This stability makes it a subject of interest for researchers investigating the electronic and structural behaviors of ternary chalcogenides.
Key Properties
Cross-validated computational properties for AlAgS2, 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.
