Van Hove singularities, chemical pressure and phonons: an angle-resolved photoemission study of KFeAs and CsFeAs
P. Richard, A. van Roekeghem, X. Shi +6
We report an angle-resolved photoemission spectroscopy (ARPES) study of KFeAs and CsFeAs, revealing the existence of a van Hove singularity affecting the electronic…
Direct spectroscopic evidence for completely filled Cu shell in BaCuAs and -BaCuSb
S. F. Wu, P. Richard, A. van Roekeghem +9
We use angle-resolved photoemission spectroscopy to extract the band dispersion and the Fermi surface of BaCuAs and -BaCuSb. While the Cu bands in both mate…
Tuning electronic correlations in transition metal pnictides: chemistry beyond the valence count
E. Razzoli, C. E. Matt, M. Kobayashi +14
The effects of electron-electron correlations on the low-energy electronic structure and their relationship with unconventional superconductivity are central aspects in the researc…
Observation of strong-coupling pairing with weakened Fermi-surface nesting at optimal hole doping in CaNaFeAs
Y. -B. Shi, Y. -B. Huang, X. -P. Wang +12
We report an angle-resolved photoemission investigation of optimally-doped CaNaFeAs. The Fermi surface topology of this compound is similar to that of the…
ARPES observation of isotropic superconducting gaps in isovalent Ru-substituted Ba(FeRu)As
N. Xu, P. Richard, X. -P. Wang +13
We used high-energy resolution angle-resolved photoemission spectroscopy to extract the momentum dependence of the superconducting gap of Ru-substituted Ba(FeRu)$…
Observation of an isotropic superconducting gap at the Brillouin zone center of TlKFeSe
X. -P. Wang, P. Richard, A. van Roekeghem +10
We performed a high-resolution angle-resolved photoemission spectroscopy study on superconducting (SC) TlKFeSe ( K) in the whole Brillouin zo…
