Rb3P
Rb3P is a semiconducting rubidium phosphide compound that is characterized by its metastable nature and structural complexity.
About Rb3P
Rb3P is a binary phosphide composed of rubidium and phosphorus. As a semiconducting material, it represents a specialized chemical system that has been characterized across multiple structural configurations in various computational databases. Its electronic nature makes it a subject of interest for fundamental studies in solid-state chemistry.
Because this compound is found above the thermodynamic hull, it is considered inherently unstable under standard conditions. This metastability suggests that while it can be modeled and theoretically identified, its synthesis and long-term preservation present significant challenges compared to more robust, ground-state materials.
Key Properties
Cross-validated computational properties for Rb3P, 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.
