YbC2
YbC2 is a thermodynamically stable semiconducting ytterbium carbide used in fundamental materials research.
About YbC2
YbC2 is a binary carbide composed of ytterbium and carbon. As a thermodynamically stable phase located on the convex hull, it represents a robust crystalline arrangement that maintains structural integrity under standard conditions. Its electronic character is defined as semiconducting, distinguishing it from metallic or insulating alternatives within the broader family of rare-earth carbides.
This compound is of significant interest in materials science due to its structural versatility, as evidenced by the numerous reported configurations across multiple databases. Its ability to adopt different structural motifs makes it a compelling subject for studies regarding phase stability and electronic behavior in lanthanide-based carbon systems.
Key Properties
Cross-validated computational properties for YbC2, 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.
