C4Zr4
C4Zr4 is a thermodynamically stable, semiconducting ultra-high-temperature ceramic used in advanced materials research.
About C4Zr4
C4Zr4 is a structurally distinct member of the ultra-high-temperature ceramic family, characterized by its robust thermodynamic stability on the convex hull. As a semiconducting compound, it offers unique electronic properties that differentiate it from the more metallic-like carbides commonly found in this class.
This material is of significant interest for high-performance engineering applications where thermal resilience is paramount. Its presence across multiple structural databases highlights its importance as a subject of fundamental materials science research into refractory compounds.
Key Properties
Cross-validated computational properties for C4Zr4, aggregated across 5 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.
