Observation of Coulomb blockade and Coulomb staircases in superconducting Pr0.8Sr0.2NiO2 films
Rui-Feng Wang, Yan-Ling Xiong, Hang Yan +7
Motivated by the discovery of superconductivity in the infinite-layer nickelate family, we report an experimental endeavor to clean the surface of nickelate superconductor Pr0.8Sr0…
Anomalous superconducting proximity effect of planar Pb-RhPb2 heterojunctions in the clean limit
Rui-Feng Wang, Yan-Ling Xiong, Qun Zhu +5
Interest in superconducting proximity effect has been revived by the exploitation of Andreev states and by the possible emergence of Majorana bound states at the interface. Spectro…
Direct observation of nodeless superconductivity and phonon modes in electron-doped copper oxide SrNdCuO
Jia-Qi Fan, Xue-Qing Yu, Fang-Jun Cheng +8
The microscopic understanding of high-temperature superconductivity in cuprates has been hindered by the apparent complexity of crystal structures in these materials. We used scann…
