ZrGeN2
ZrGeN2 is a semiconducting ternary nitride compound belonging to the MAX phase family that exists as a metastable structure.
About ZrGeN2
ZrGeN2 is a ternary nitride compound that belongs to the broader class of MAX-like phases. It exhibits semiconducting electronic behavior, positioning it as an interesting candidate for specialized electronic or optoelectronic research applications where specific band structures are required. The material is characterized by its position above the thermodynamic hull, suggesting it is a metastable phase. Its existence across multiple reported structures highlights the complex landscape of zirconium-germanium-nitrogen chemistry and the challenges associated with synthesizing stable, high-purity nitride phases.
Key Properties
Cross-validated computational properties for ZrGeN2, 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.
