Enhancement of superconductivity in electron-hole coexisting SrEuCuO films
Hang Yan, Ze-Xian Deng, Xue-Qing Yu +6
We report transport measurements of infinite-layer cuprate SrEuCuO films with controlled electron (by trivalent europium) and hole (by interstitial apical oxy…
Quantum spin driven Yu-Shiba-Rusinov multiplets and fermion-parity-preserving phase transition in KC
Shu-Ze Wang, Xue-Qing Yu, Li-Xuan Wei +9
Magnetic impurities in superconductors are of increasing interest due to emergent Yu-Shiba-Rusinov (YSR) states and Majorana zero modes for fault-tolerant quantum computation. Howe…
Percolative Superconductivity in Electron-Doped SrEuCuO Films
Xue-Qing Yu, Hang Yan, Li-Xuan Wei +7
Electron-doped infinite-layer SrEuCuO films over a wide doping range have been prepared epitaxially on SrTiO(001) using reactive molecular beam epitaxy. I…
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…
Molecular beam epitaxy growth and surface structure of Sr1-xNdxCuO2 cuprate films
Jia-Qi Fan, Shu-Ze Wang, Xue-Qing Yu +5
We report on the epitaxial growth and surface structure of infinite-layer cuprate Sr1-xNdxCuO2 films on SrTiO3(001) substrates by combining ozone-assisted molecular beam epitaxy an…
Stoichiometry and defect superstructures in epitaxial FeSe films on SrTiO3
Xue-Qing Yu, Ming-Qiang Ren, Yi-Min Zhang +5
Cryogenic scanning tunneling microscopy is employed to investigate the stoichiometry and defects of epitaxial FeSe thin films on SrTiO3(001) substrates under various post-growth an…
Direct visualization of ambipolar Mott transition in cuprate CuO2 planes
Yong Zhong, Jia-Qi Fan, Ruifeng Wang +11
Identifying the essence of doped Mott insulators is one of the major outstanding problems in condensed matter physics and the key to understanding the high-temperature superconduct…
