MgP
MgP is a metallic magnesium phosphide compound that exists in a metastable state.
About MgP
MgP is a metallic phosphide compound characterized by its lack of a band gap. As a material that sits above the thermodynamic hull, it is considered inherently unstable under standard conditions, representing a metastable phase of interest in fundamental materials science studies. Despite its instability, it has been the subject of significant structural investigation, appearing in numerous reported configurations across multiple databases. This high level of structural data suggests that while it may not be a conventional stable ground-state material, it remains a notable subject for researchers exploring the complex phase space of magnesium-phosphorus systems.
Key Properties
Cross-validated computational properties for MgP, 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.

How It Compares
As a unique binary compound in this system, MgP serves as a distinct point of study for understanding the structural diversity of magnesium phosphides.
