Emerging NO2 gas sensing on substitutionally doped Fe on NiWO4 SCES insulators

Emerging NO2 gas sensing on substitutionally doped Fe on NiWO4 SCES insulators

In this study, we demonstrate the emergence of NO2 gas sensing capabilities in the typically non-active NiWO4, a strongly correlated electron system (SCES), by introducing substitutional Fe at the Ni site. NiWO4 typically exhibits strong Coulombic repulsion between Ni atoms, resulting in a large ban...
