Alabandite is a stable, metallic manganese sulfide compound widely studied for its structural and electronic properties.
About alabandite
Alabandite is a naturally occurring manganese sulfide that maintains a stable position on the thermodynamic convex hull. As a metallic compound, it exhibits distinct electronic properties that differentiate it from typical insulating metal sulfides. Its structural reliability is underscored by its extensive documentation across multiple scientific databases, reflecting its importance in inorganic chemistry research. This compound serves as a critical model for understanding transition metal chalcogenides and their fundamental electronic behaviors. Its stability makes it a robust subject for studying phase transitions and magnetic properties in sulfide systems.
Key Properties
Cross-validated computational properties for alabandite, aggregated across 5 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.
