MgCo2Si
MgCo2Si is a metastable semiconducting ternary compound composed of magnesium, cobalt, and silicon.
About MgCo2Si
MgCo2Si is a ternary compound composed of magnesium, cobalt, and silicon. As a semiconducting material, it exhibits electronic characteristics that distinguish it from purely metallic or insulating phases, making it a subject of interest for fundamental solid-state research.
This material is classified as metastable, indicating that it exists in a state that requires specific synthesis conditions to maintain its structure. With multiple reported structural variations across databases, it remains a significant candidate for studies regarding phase stability and electronic behavior in complex ternary systems.
Key Properties
Cross-validated computational properties for MgCo2Si, 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.
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.
