About barium phosphide
Barium phosphide is a binary inorganic compound composed of barium and phosphorus. As a thermodynamically stable material situated on the convex hull, it exhibits robust structural integrity, making it a reliable subject for research into phosphide-based semiconductors. Its electronic character suggests potential utility in specialized electronic or optoelectronic device architectures where specific semiconducting behaviors are required. The material is characterized by its structural diversity, with multiple reported configurations across major materials databases, highlighting its significance in solid-state chemistry. This versatility allows researchers to investigate how different atomic arrangements influence its fundamental properties, contributing to the broader understanding of alkaline earth metal pnictides.
Key Properties
Cross-validated computational properties for barium phosphide, 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.
