Universality of superconducting gaps in overdoped Ba0.3K0.7Fe2As2 observed by angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, P. Richard +8
We have performed angle-resolved photoemission spectroscopy on the overdoped BaKFeAs superconductor ( = 22 K). We demonstrate that the superconducting…
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…
Unconventional superconducting gap in NaFeCoAs observed by angle-resolved photoemission spectroscopy
Z. -H. Liu, P. Richard, K. Nakayama +16
We have performed high resolution angle-resolved photoemission measurements on superconducting electron-doped NaFeCoAs (18 K). We observed a hole-like…
Electron-Hole Asymmetry in Superconductivity of Pnictides Originated from the Observed Rigid Chemical Potential Shift
M. Neupane, P. Richard, Y. -M. Xu +12
We have performed a systematic photoemission study of the chemical potential shift as a function of carrier doping in a pnictide system based on BaFeAs. The experimentally…
Observation of an Orbital Selective Electron-Mode Coupling in Fe-Based High- Superconductors
P. Richard, T. Sato, K. Nakayama +7
We have performed an angle-resolved photoemission spectroscopy study of the new superconductor BaKFeAs in the low energy range. We report the observation of…
Angle-Resolved Photoemission Spectroscopy of the Antiferromagnetic Superconductor Nd1.87Ce0.13CuO4: Anisotropic Spin-Correlation Gap, Pseudogap, and the Induced Quasiparticle Mass Enhancement
H. Matsui, K. Terashima, T. Sato +6
We performed high-resolution angle-resolved photoemission spectroscopy on Nd1.87Ce0.13CuO4, which is located at the boundary of the antiferromagnetic (AF) and the superconducting p…
Quasiparticles in the superconducting state of Bi2Sr2CaCu2O8
A. Kaminski, J. Mesot, H. Fretwell +9
Recent improvements in momentum resolution by a factor of 32 lead to qualitatively new ARPES results on the spectra of Bi2Sr2CaCu2O8 (Bi2212) along the (pi,pi) direction, where the…
Temperature-induced spectral weight transfer in Bi_2Sr_2CaCu_2O_{8+delta}: a conventional view
J. C. Campuzano, H. Ding, H. Fretwell +6
In contrast with the recent photoemission observations by Shen et al. of anomalous temperature-induced momentum-dependent spectral weight transfer in Bi_2Sr_2CaCu_2O_{8+delta}, we…
ARPES study of the superconducting gap and pseudogap in Bi2Sr2CaCu2O8+x
H. Ding, J. C. Campuzano, M. R. Norman +8
In this paper, we review some of our ARPES results on the superconducting and pseudo gaps in Bi2Sr2CaCu2O8+x. We find that optimally and overdoped samples exhibit a d-wave gap, whi…
