Observation of an electron band above the Fermi level in FeTeSe from \emph{in-situ} surface doping
P. Zhang, P. Richard, N. Xu +7
We used \emph{in-situ} potassium (K) evaporation to dope the surface of the iron-based superconductor FeTeSe. The systematic study of the bands near the Fermi lev…
Orbital Characters Determined from Fermi Surface Intensity Patterns using Angle-Resolved Photoemission Spectroscopy
X. -P. Wang, P. Richard, Y. -B. Huang +10
In order to determine the orbital characters on the various Fermi surface pockets of the Fe-based superconductors BaKFeAs and FeSeTe,…
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…
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 Dirac Cone Electronic Dispersion in BaFe2As2
P. Richard, K. Nakayama, T. Sato +8
We performed an angle-resolved photoemission spectroscopy study of BaFe2As2, which is the parent compound of the so-called 122 phase of the iron-pnictide high-temperature supercond…
Fermi surface dichotomy of the superconducting gap and pseudogap in underdoped pnictides
Y. -M. Xu, P. Richard, K. Nakayama +15
High-temperature superconductivity in iron-arsenic materials (pnictides) near an antiferromagnetic phase raises the possibility of spin-fluctuation-mediated pairing. However, the i…
