DyP5
DyP5 is a thermodynamically stable, semimetallic compound formed from dysprosium and phosphorus.
About DyP5
DyP5 is a binary phosphide compound composed of dysprosium and phosphorus. As a thermodynamically stable phase located on the convex hull, it represents a robust structural arrangement within the rare-earth phosphide family.
This material exhibits a near-zero-gap electronic character, positioning it as a semimetallic conductor. Its structural integrity and electronic properties make it a subject of interest for fundamental research into rare-earth-based electronic systems.
Key Properties
Cross-validated computational properties for DyP5, 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.
