MgSnP2
MgSnP2 is a semiconducting ternary phosphide compound that is considered potentially synthesizable due to its favorable thermodynamic stability.
About MgSnP2
MgSnP2 is a ternary phosphide characterized by its semiconducting electronic nature. Its position near the thermodynamic stability hull suggests that it is a viable target for experimental synthesis and potential integration into functional devices.
As a material with multiple reported structural variations, it represents an interesting subject for solid-state research. Its chemical composition and electronic properties position it as a candidate for specialized applications where specific semiconducting behaviors are required.
Key Properties
Cross-validated computational properties for MgSnP2, 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.
