Fe-based superconductors: an angle-resolved photoemission spectroscopy perspective
P. Richard, T. Sato, K. Nakayama +2
Angle-resolved photoemission spectroscopy allows direct visualization and experimental determination of the electronic structure of crystals in the momentum space, including the pr…
Local antiferromagnetic exchange and collaborative Fermi surface as key ingredients of high temperature superconductors
Jiangping Hu, Hong Ding
Cuprates, ferropnictides and ferrochalcogenides are three classes of unconventional high-temperature superconductors, who share similar phase diagrams in which superconductivity de…
Isotropic superconducting gaps with enhanced pairing on electron Fermi surfaces in FeTe0.55Se0.45
H. Miao, P. Richard, Y. Tanaka +17
The momentum distribution of the energy gap opening at the Fermi level of superconductors is a direct fingerprint of the pairing mechanism. While the phase diagram of the iron-base…
Two pseudogaps with different energy scales at the antinode of the high-temperature BiSrCuO superconductor using angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, Y. -M. Xu +8
We have performed high-resolution angle-resolved photoemission spectroscopy on single-layered cuprate BiSrCuO to clarify the origin of the pseudogap. By using various p…
Strong nodeless pairing on separate electron Fermi surface sheets in (Tl, K)FeSe probed by ARPES
X. -P. Wang, T. Qian, P. Richard +6
We performed a high-resolution angle-resolved photoemission spectroscopy study of the TlKFeSe superconductor ( K). We show the existence of t…
