About nickel ditelluride
Nickel ditelluride is a metallic compound composed of nickel and tellurium. As a thermodynamically stable phase, it maintains a robust structural integrity that makes it a subject of significant interest in materials science research. Its metallic nature distinguishes it from many other dichalcogenides that exhibit semiconducting behavior.
Due to its high structural diversity, this compound has been extensively documented across multiple databases. Its stability and electronic characteristics suggest potential utility in applications requiring conductive transition metal-based thin films or catalytic surfaces.
Key Properties
Cross-validated computational properties for nickel ditelluride, 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.
