InCN2
InCN2 is a semiconducting nitride compound containing carbon that is primarily studied for its structural complexity and electronic properties.
About InCN2
InCN2 is a semiconducting compound characterized by its unique combination of indium, carbon, and nitrogen. As a member of the nitride semiconductor family, it represents a complex structural arrangement that has been the subject of significant investigation across multiple materials databases.
While its thermodynamic stability indicates it sits above the hull, the existence of several reported structures highlights its importance in fundamental materials research. Understanding its electronic behavior is essential for mapping the potential of carbon-containing nitrides in advanced semiconductor applications.
Key Properties
Cross-validated computational properties for InCN2, 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.

| Space GroupSymmetry classification of the crystal arrangement. The number is the international space-group index. | Crystal SystemBroad lattice family, such as cubic, tetragonal, monoclinic, or triclinic, derived from unit-cell symmetry. | Band Gap (eV)Electronic gap calculated for this specific reported structure, measured in electronvolts. | E above hull (eV/atom)Thermodynamic distance from the convex hull for this structure, normalized per atom. Lower is generally more stable. | E/atom (eV)Computed total energy normalized per atom.

How It Compares
Within the nitride semiconductors class.
InCN2 occupies a distinct position compared to more conventional nitride semiconductors like GaN or InN. Unlike these highly stable, industrially established binary nitrides, InCN2 incorporates carbon into its lattice, placing it in a specialized category alongside complex materials like BC2N rather than the standard III-V semiconductor group.
