About Zr2SeN2
Zr2SeN2 is a distinct inorganic compound characterized by its semiconducting electronic nature. Its position on the convex hull confirms that it is a thermodynamically stable phase, making it a robust candidate for structural and functional analysis in solid-state chemistry.
Given its unique combination of zirconium, selenium, and nitrogen, this material is of significant interest for researchers investigating new ternary systems. Its stability suggests potential for integration into specialized electronic or optoelectronic device architectures where stable semiconducting behavior is required.
Key Properties
Cross-validated computational properties for Zr2SeN2, 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.
