From perovskite to infinite-layer nickelates: hole concentration from x-ray absorption
R. Pons, M. Flavenot, K. Fürsich +12
The difficulty of determining cation concentrations and oxygen stoichiometry in infinite-layer nickelate thin films has so far prevented clear experimental identification of the ni…

Direct imaging of disordered residual oxygen and its impact on electronic structure in an infinite-layer nickelate superlattice
Chao Yang, Hongguang Wang, Roberto A. Ortiz +4
Infinite layer nickelates have garnered significant attention due to their potential for high-temperature superconductivity. Despite extensive research, the interplay between oxyge…

Oxygen sublattice disorder and valence state modulation in infinite-layer nickelate superlattices
R. A. Ortiz, N. Enderlein, K. Fürsich +9
The family of infinite-layer nickelates promises important insights into the mechanism of unconventional superconductivity. Since superconductivity has so far only been observed in…
