Bond formation at the Ni/ZrO_(2) interface

We report on the formation of strong chemical bonds at the Ni(100)/cubic-ZrO_(2)(100) polar interfaces. Ab initio density functional theory calculations demonstrate that both Zr/Ni and O/Ni junctions are energetically stable, and predict that two different interactions determine the interface adhesi...

Sumario:We report on the formation of strong chemical bonds at the Ni(100)/cubic-ZrO_(2)(100) polar interfaces. Ab initio density functional theory calculations demonstrate that both Zr/Ni and O/Ni junctions are energetically stable, and predict that two different interactions determine the interface adhesion. Our results reveal that O-Ni ionic bonds are formed by Ni electron donation, while the Zr-Ni bonds show a mixed character with ionic and electron hybridization contributions.
