AlBaS2
AlBaS2 is a thermodynamically stable, wide-gap insulating sulfide compound.
About AlBaS2
AlBaS2 is a ternary sulfide compound that exists as a thermodynamically stable phase on the convex hull. Its electronic character is defined by a wide-gap insulating nature, which makes it a subject of interest for researchers investigating specialized dielectric or optical materials. The compound exhibits structural diversity, with multiple reported configurations across materials databases. This structural flexibility highlights its potential for tuning physical properties through synthesis control. As a stable sulfide, it serves as a foundational building block for exploring complex chalcogenide systems where insulating behavior is required for device performance. Its role in materials science is primarily focused on fundamental exploration of its electronic and structural stability.
Key Properties
Cross-validated computational properties for AlBaS2, 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.
