About CrP2
CrP2 is a metallic chromium phosphide characterized by its distinct electronic structure. As a material that lacks a band gap, it exhibits properties typical of conductors, making it a subject of interest for fundamental studies in transition metal phosphides.
Due to its near-hull thermodynamic stability, this compound is considered a promising candidate for experimental synthesis. Its presence across multiple structural databases highlights its significance as a well-documented phase in the chromium-phosphorus system.
Key Properties
Cross-validated computational properties for CrP2, aggregated across 4 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.
