CaGeN
CaGeN is a semiconducting ternary nitride compound that is currently classified as a metastable material.
About CaGeN
CaGeN is a ternary nitride compound composed of calcium, germanium, and nitrogen. It exhibits semiconducting electronic properties, placing it in a category of materials often investigated for potential optoelectronic or specialized electronic applications.
As a material that sits above the thermodynamic hull, CaGeN is considered metastable. Its existence in multiple reported structures across various databases highlights the ongoing scientific interest in characterizing the complex phase space of calcium-germanium-nitrogen systems.
Key Properties
Cross-validated computational properties for CaGeN, 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 CaGeN. 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.
