CCuNS
CCuNS is a semiconducting inorganic compound containing copper, carbon, nitrogen, and sulfur that exhibits metastable thermodynamic behavior.
About CCuNS
CCuNS is a complex inorganic material characterized by its semiconducting electronic nature. Its composition, involving copper, carbon, nitrogen, and sulfur, places it in a specialized category of materials that bridge the gap between organic and inorganic coordination chemistry. Due to its electronic profile, it is a subject of interest for fundamental research into how these specific elements interact within a crystal lattice.
While multiple structural configurations have been documented in databases, the compound is identified as being thermodynamically unstable relative to its constituent phases. This metastability suggests that while it can exist in specific synthetic conditions, it likely requires precise control over its environment to maintain its structural integrity for potential future applications.
Key Properties
Cross-validated computational properties for CCuNS, 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.
