Marginal-Fermi-Liquid-like Behavior without Pseudogap in Infinite-Layer Nickelates
Yu Fan, Zhitong An, Xiang Ding +10
Pseudogap formation, strange-metal behavior and unconventional superconductivity are closely intertwined in hole-doped cuprates, yet their relationship remains unresolved. Infinite…
A Disconnected Superconducting Regime at the Parent Limit of Infinite-Layer Nickelates
Chihao Li, Yutong Chen, Yaolong Bian +11
Infinite-layer nickelates have been widely viewed as cuprate analogs in which superconductivity emerges and forms a superconducting dome centered around 10-20% cation substitution.…
Thermoelectricity evidence for quantum criticality in clean infinite-layer nickelate films
Xu Zhang, Chihao Li, Mingwei Yang +8
We investigate the Seebeck coefficient () in infinite-layer nickelate films with different disorder levels. The disordered NdNiO film exhibits a flat curve, whereas…
Observation of Electride-like States Coexisting with Correlated Electrons in NdNiO
Chihao Li, Yutong Chen, Xiang Ding +13
Despite exhibiting a similar band character to cuprates, infinite-layer nickelates host additional electron pockets that distinguish them from single-band cuprates. T…
