CeNiGe
CeNiGe is a stable semimetallic intermetallic compound composed of cerium, nickel, and germanium.
About CeNiGe
CeNiGe is a thermodynamically stable ternary intermetallic compound that sits directly on the convex hull, indicating high structural integrity. Its electronic character is defined as a near-zero-gap semimetal, placing it in a unique regime where conduction behavior is sensitive to subtle structural variations.
Because of its robust stability and distinct electronic profile, this material serves as an important subject for fundamental research into rare-earth nickel germanides. It is frequently studied for its potential role in understanding complex magnetic and electronic phase transitions in intermetallic systems.
Key Properties
Cross-validated computational properties for CeNiGe, 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.
