CsP7
CsP7 is a stable, semiconducting binary phosphide compound composed of cesium and phosphorus.
About CsP7
CsP7 is a thermodynamically stable binary phosphide that exists on the convex hull, indicating significant structural robustness. As a semiconducting material, it offers unique electronic properties that distinguish it from metallic or insulating phosphorus-rich compounds.
Its existence across multiple structural databases highlights its importance in solid-state chemistry. Researchers study this compound to better understand the complex bonding environments of phosphorus networks stabilized by alkali metal cations.
Key Properties
Cross-validated computational properties for CsP7, 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.
