CeMg
CeMg is a semiconducting intermetallic compound composed of cerium and magnesium that is considered potentially synthesizable due to its thermodynamic stability.
About CeMg
CeMg is a semiconducting binary intermetallic compound composed of cerium and magnesium. Its electronic properties and structural configuration make it a subject of significant interest for researchers exploring novel functional materials with specific semiconducting behavior. The material is recognized for its proximity to the thermodynamic hull, suggesting it is a viable candidate for experimental synthesis and further characterization in laboratory settings. Given the extensive structural data available across multiple databases, CeMg represents a well-documented entry in the landscape of cerium-based alloys. Its potential utility lies in its unique electronic character, which distinguishes it from more common metallic alloys and positions it for specialized applications in materials science.
Key Properties
Cross-validated computational properties for CeMg, 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.
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 CeMg. 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.
Space Group ConsensusWhether independent sources predict the same crystal symmetry for the lowest-energy structure.
