About Magnesium sulfide
Magnesium sulfide is a binary inorganic compound that exists as a thermodynamically stable phase. Due to its wide-gap insulating electronic character, it serves as a fundamental material for investigating the behavior of alkaline earth chalcogenides in solid-state chemistry. Its structural reliability is evidenced by its presence on the convex hull, making it a robust subject for theoretical and experimental studies. The compound is frequently utilized in research contexts to understand ionic bonding and lattice dynamics in simple binary systems. Beyond its fundamental scientific value, it is explored for its potential in specialized electronic and optical applications where insulating properties are required.
Key Properties
Cross-validated computational properties for Magnesium sulfide, aggregated across 6 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.
