About K2CN2
K2CN2 is a crystalline solid composed of potassium, carbon, and nitrogen. As a thermodynamically stable phase located on the convex hull, it represents a robust configuration within its chemical system, characterized by its insulating electronic nature and wide band gap.
This material is of significant interest for fundamental research into carbon-nitrogen frameworks. Its stability and electronic properties make it a subject of study for understanding how alkali metals influence the bonding and structural arrangement of cyanamide-based anions.
Key Properties
Cross-validated computational properties for K2CN2, 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.
