About C2N
C2N is a distinct carbon-nitrogen compound characterized by its wide-band-gap insulating electronic profile. Its unique atomic arrangement makes it a subject of significant interest in computational materials science, where researchers explore its potential for specialized electronic and optoelectronic applications.
While current data suggests it resides above the thermodynamic hull, indicating potential metastability, the existence of numerous reported structures highlights its structural complexity. This compound serves as a fascinating case study for understanding nitrogen-doped carbon frameworks and their synthetic pathways.
Key Properties
Cross-validated computational properties for C2N, aggregated across 4 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of C2N. Tight agreement means computed properties can be trusted without re-running calculations.
