Is BaCrAs symmetrical to BaFeAs with respect to half shell filling?
P. Richard, A. van Roekeghem, B. Q. Lv +7
We have performed an angle-resolved photoemission spectroscopy study of BaCrAs, which has the same crystal structure as BaFeAs, a parent compound of Fe-based superc…
Enhanced superconductivity accompanying a Lifshitz transition in electron-doped FeSe monolayer
X. Shi, Z. -Q. Han, X. -L. Peng +8
The origin of enhanced superconductivity over 50 K in the recently discovered FeSe monolayer films grown on SrTiO (STO), as compared to 8 K in bulk FeSe, is intensely debated…
Observation of non-Fermi liquid behavior in hole-doped LiFeVAs
L. Y. Xing, X. Shi, P. Richard +12
We synthesized a series of V-doped LiFeVAs single crystals. The superconducting transition temperature of LiFeAs decreases rapidly at a rate of 7 K per 1\% V. The…
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…
Observation of momentum-confined in-gap impurity state in BaKFeAs: evidence for anti-phase pairing
P. Zhang, P. Richard, T. Qian +12
We report the observation by angle-resolved photoemission spectroscopy of an impurity state located inside the superconducting gap of BaKFeAs and vanishing…
Possible nodal superconducting gap emerging at the Lifshitz transition in heavily hole-doped Ba0.1K0.9Fe2As2
N. Xu, P. Richard, X. Shi +11
We performed a high energy resolution ARPES investigation of over-doped Ba0.1K0.9Fe2As2 with T_c= 9 K. The Fermi surface topology of this material is similar to that of KFe2As2 and…
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…
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…
