platinum dinitride · platinum nitride
Platinum dinitride is a semiconducting compound of platinum and nitrogen that is frequently studied for its diverse structural phases despite its inherent thermodynamic instability.
About platinum dinitride
Platinum dinitride is a binary compound composed of platinum and nitrogen. It exhibits semiconducting electronic behavior, positioning it as an interesting subject for studies into the electronic properties of transition metal nitrides.
While it has been the subject of extensive structural investigation with numerous reported configurations, it is characterized as being thermodynamically unstable relative to its elemental constituents. This metastability makes it a challenging but significant material for high-pressure synthesis research.
Key Properties
Cross-validated computational properties for platinum dinitride, 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.
