boron subphosphide · boron phosphide
Boron subphosphide is a stable, semiconducting binary compound formed from boron and phosphorus.
About boron subphosphide
Boron subphosphide is a crystalline semiconductor composed of boron and phosphorus. As a thermodynamically stable phase located on the convex hull, it exhibits robust structural integrity that makes it an intriguing candidate for specialized electronic and optoelectronic environments.
Its unique atomic arrangement allows it to maintain stability under demanding conditions. Researchers study this material to leverage its semiconducting nature for applications that require high thermal and chemical resilience, distinguishing it from more common, less stable binary compounds.
Key Properties
Cross-validated computational properties for boron subphosphide, 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.
