CeMgSe3
CeMgSe3 is a semiconducting ternary selenide compound that is currently a subject of interest in computational materials science.

About CeMgSe3
CeMgSe3 is a ternary selenide compound featuring cerium and magnesium. As a semiconducting material, it represents a specialized niche in chalcogenide research, where the interplay between rare-earth elements and alkaline earth metals dictates its electronic behavior.
While the compound has been identified across multiple structural databases, its thermodynamic profile suggests it resides above the stability hull. This indicates that the material likely requires specific synthesis conditions to be realized, marking it as a subject of interest for computational materials discovery.
Key Properties
Cross-validated computational properties for CeMgSe3, 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.
