CoGe
CoGe is a thermodynamically stable metallic compound formed from cobalt and germanium.
About CoGe
CoGe is a metallic binary intermetallic compound composed of cobalt and germanium. It is recognized for its thermodynamic stability, sitting directly on the convex hull, which indicates a robust structural configuration under standard conditions. The material is characterized by its metallic electronic nature, lacking a band gap. Its presence in multiple databases highlights its significance as a subject of interest in solid-state physics and materials science research.
Key Properties
Cross-validated computational properties for CoGe, 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.
StructuresCount of reported calculated crystal structures for this formula, including alternate polymorphs, source databases, and observed space groups.
Cross-Source DFT Agreement
How well independent DFT databases agree on the thermodynamics of CoGe. Tight agreement means computed properties can be trusted without re-running calculations.
Agreement ScoreA normalized confidence score summarizing how closely independent DFT databases agree. Higher scores mean tighter cross-source agreement.
Hull SpreadDifference between the highest and lowest energy-above-hull values reported by comparable sources. Smaller spread means less thermodynamic disagreement.
Sources ComparedNumber and names of computational sources with comparable entries for this formula.
