Effects of Ru Substitution on Dimensionality and Electron Correlations in Ba(Fe_{1-x}Ru_x)_2As_2
N. Xu, T. Qian, P. Richard +12
We report a systematic angle-resolved photoemission spectroscopy study on Ba(FeRu)As for a wide range of Ru concentrations (0.15 \emph{x} 0.74). W…
Isotropic superconducting gaps with enhanced pairing on electron Fermi surfaces in FeTe0.55Se0.45
H. Miao, P. Richard, Y. Tanaka +17
The momentum distribution of the energy gap opening at the Fermi level of superconductors is a direct fingerprint of the pairing mechanism. While the phase diagram of the iron-base…
Two pseudogaps with different energy scales at the antinode of the high-temperature BiSrCuO superconductor using angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, Y. -M. Xu +8
We have performed high-resolution angle-resolved photoemission spectroscopy on single-layered cuprate BiSrCuO to clarify the origin of the pseudogap. By using various p…
A precise method for visualizing dispersive features in image plots
P. Zhang, P. Richard, T. Qian +3
In order to improve the advantages and the reliability of the second derivative method in tracking the position of extrema from experimental curves, we develop a novel analysis met…
Fermiology of Sr4V2O6Fe2As2: Quasi-Nested Fe vs Mott-Insulating V Orbitals
T. Qian, N. Xu, Y. -B. Shi +14
We have performed an angle-resolved photoemission spectroscopy study of a new iron-based superconductor Sr4V2O6Fe2As2. While V 3d orbitals are found to be in a Mott insulator state…
Observation of a ubiquitous three-dimensional superconducting gap function in optimally-doped BaKFeAs
Y. -M. Xu, Y. -B. Huang, X. -Y. Cui +10
The iron-pnictide superconductors have a layered structureformed by stacks of FeAs planes from which the superconductivity originates. Given the multiband and quasi three-dimension…
