AuCa2P
AuCa2P is a semiconducting ternary phosphide compound that exists in a metastable state.
About AuCa2P
AuCa2P is a ternary phosphide compound characterized by its semiconducting electronic nature. As a complex inorganic material containing gold, calcium, and phosphorus, it represents a niche area of study for researchers investigating unconventional electronic configurations in metal-rich phosphides.
Due to its position above the thermodynamic hull, this compound is considered metastable. Its existence across multiple structural reports suggests that while it may not be the ground-state configuration, specific synthesis conditions can stabilize this unique chemical arrangement.
Key Properties
Cross-validated computational properties for AuCa2P, 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.
