Observation of Dirac-like band dispersion in LaAgSb $_{2}$

X. Shi, P. Richard, Kefeng Wang +10

We present a combined angle-resolved photoemission spectroscopy (ARPES) and first-principles calculations study of the electronic structure of LaAgSb $_{2}$ in the entire first Brillo…

Observation of an electron band above the Fermi level in FeTe $_{0.55}$ Se $_{0.45}$ 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 FeTe $_{0.55}$ Se $_{0.45}$ . 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…

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…

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…
