Camelback-shaped band reconciles heavy electron behavior with weak electronic Coulomb correlations in superconducting TlNi2Se2
N. Xu, C. E. Matt, P. Richard +16
Using high-resolution photoemission spectroscopy and first-principles calculations, we characterize superconducting TlNiSe as a material with weak electronic Coulomb correl…
Observation of a van Hove singularity and implication for strong coupling induced Cooper pairing in KFe2As2
Delong Fang, Xun Shi, Zengyi Du +14
Scanning tunneling spectroscopy (STS) and angle-resolved photoemission spectroscopy (ARPES) have been investigated on single crystal samples of KFe2As2. A van Hove singularity (vHs…
Growth of (NaxKy)FezSe2 crystals by chlorides flux at low temperatures
Gang Wang, Tianping Ying, Yaobo Huang +4
(NaxKy)FezSe2 crystals are prepared by Na, Fe, and Se as starting materials in NaCl/KCl flux at low temperatures~720 °C. It is found that K is more preferred than Na to enter in be…
Raman scattering investigation of the electron-phonon coupling in superconducting Nd(O,F)BiS
S. F. Wu, P. Richard, X. B. Wang +5
We have performed polarized Raman scattering measurements on the newly discovered superconductor Nd(O,F)BiS ( K). We observe 2 Raman active modes, with frequencies in…
Raman scattering investigation of superconducting BaTiFeAsO
S. -F. Wu, P. Richard, W. -L. Zhang +5
We have performed polarized Raman scattering measurements on the newly discovered superconductor BaTiFeAsO ( K). We observe seven out of eig…
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 anomalous temperature dependence of spectrum on small Fermi surfaces in a BiS2-based superconductor
L. K. Zeng, X. B. Wang, J. Ma +7
We performed an angle-resolved photoemission spectroscopy study of the BiS2-based superconductor Nd(O,F)BiS2. Two small electron-like Fermi surfaces around X (pi, 0) are observed,…
