On the origin of the electronic anisotropy in iron pnicitde superconductors
W. -L. Zhang, P. Richard, H. Ding +5
We use polarization-resolved Raman spectroscopy to study the anisotropy of the electronic characteristics of the iron-pnictide parent compounds FeAs (~=~Eu, Sr).…
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…
Correlation-induced self-doping in intercalated iron-pnictide superconductor Ba2Ti2Fe2As4O
Junzhang Ma, Ambroise van Roekeghem, Pierre Richard +14
The electronic structure of the intercalated iron-based superconductor Ba2Ti2Fe2As4O (Tc - 21.5 K) has been investigated by using angle-resolved photoemission spectroscopy and comb…
Raman scattering investigation of the electron-phonon coupling in superconducting Nd(O,F)BiS
S. F. Wu, P. Richard, X. B. Wang +5
We have performed polarized Raman scattering measurements on the newly discovered superconductor Nd(O,F)BiS ( K). We observe 2 Raman active modes, with frequencies in…
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…
Evolution from incoherent to coherent electronic states and its implications to superconductivity in FeTe1-xSex
E. Ieki, K. Nakayama, Y. Miyata +14
We have performed systematic angle-resolved photoemission spectroscopy (ARPES) of iron-chalcogenide superconductor FeTe1-xSex to elucidate the electronic states relevant to the sup…
