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…
Continuous doping of a cuprate surface: new insights from in-situ ARPES
Y. G. Zhong, J. Y. Guan, X. Shi +10
The cuprate superconductors distinguish themselves from the conventional superconductors in that a small variation in the carrier doping can significantly change the superconductin…
Electron scattering, charge order, and pseudogap physics in LaNdSrCuO: An angle resolved photoemission spectroscopy study
Christian E. Matt, Claudia G. Fatuzzo, Y. Sassa +27
We report an angle-resolved photoemission study of the charge stripe ordered LaNdSrCuO system. A comparative and quantitative line shape analysis is prese…
Observation of strong electron pairing on bands without Fermi surfaces in LiFe1-xCoxAs
H. Miao, T. Qian, X. Shi +8
In conventional BCS superconductors, the quantum condensation of superconducting electron pairs is understood as a Fermi surface (FS) instability, in which the low-energy electrons…
Structural phase transition induced by van Hove singularity in 5d transition metal compound IrTe2
T. Qian, H. Miao, Z. J. Wang +17
Comprehensive studies of the electronic states of Ir 5d and Te 5p have been performed to elucidate the origin of the structural phase transition in IrTe2 by combining angle-resolve…
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)$…
