Role of anion in the pairing interaction of iron-based superconductivity
J. -X. Yin, Y. Y. Zhao, Zheng Wu +20
High-temperature iron-based superconductivity develops in a structure with unusual lattice-orbital geometry, based on a planar layer of Fe atoms with 3d orbitals and tetrahedrally…
Cooper Pairing and Phase Coherence in Iron Superconductor Fe1+x(Te,Se)
J. -X. Yin, Zheng Wu, X. Huang +14
The Cooper pairing and phase coherence are two fundamental aspects of superconductivity. Due to breaking time reversal symmetry, magnetic impurities are detrimental to superconduct…
Role of Arsenic in Iron-based Superconductivity at Atomic Scale
J. -X. Yin, Zheng Wu, X. X. Wu +15
In iron-based superconductors, a unique tri-layer Fe-As (Se, Te, P) plays an essential role in controlling the electronic properties, especially the Cooper pairing interaction. Her…
Surface terminations and layer-resolved spectroscopy in 122 iron pnictide superconductors
Ang Li, J. -X. Yin, Jihui Wang +13
The surface terminations of 122-type alkaline earth metal iron pnictides AEFe2As2 (AE = Ca, Ba) are investigated with scanning tunneling microscopy/spectroscopy (STM/STS). Cleaving…
Orbital selectivity of layer resolved tunneling on iron superconductor Ba0.6K0.4Fe2As2
J. -X. Yin, X. -X. Wu, Jian Li +15
We use scanning tunneling microscopy/spectroscopy (STM/S) to elucidate the Cooper pairing of the iron pnictide superconductor Ba0.6K0.4Fe2As2. By a cold-cleaving technique, we obta…
Observation of a Robust Zero-energy Bound State in Iron-based Superconductor Fe(Te,Se)
J. -X. Yin, Zheng Wu, J. -H. Wang +14
A robust zero-energy bound state (ZBS) in a superconductor, such as a Majorana or Andreev bound state, is often a consequence of non-trivial topological or symmetry related propert…
Observation of multiple superconducting gaps in Fe1+yTe1-xSex via a nano-scale approach to point-contact spectroscopy
Haibing Peng, Debtanu De, Zheng Wu +1
We report a distinct experimental approach to point-contact Andreev reflection spectroscopy with diagnostic capability via a unique design of nano-scale normal metal/superconductor…
