By combining angle-resolved photoemission spectroscopy and quantum oscillation measurements, we performed a comprehensive investigation on the electronic structure of LaSb, which e…
Emergence of topological bands on the surface of ZrSnTe crystal
R. Lou, J. -Z. Ma, Q. -N. Xu +12
By using angle-resolved photoemission spectroscopy combined with first-principles calculations, we reveal that the topmost unit cell of ZrSnTe crystal hosts two-dimensional (2D) el…
Observation of high-Tc superconductivity in rectangular FeSe/STO(110) monolayer
P. Zhang, X. -L. Peng, T. Qian +12
It is well known that superconductivity in Fe-based materials is favoured under tetragonal symmetry, whereas competing orders such as spin-density-wave (SDW) and nematic orders eme…
Spin-Fluctuation-Induced Non-Fermi-Liquid Behavior with suppressed superconductivity in LiFeCoAs
Y. M. Dai, H. Miao, L. Y. Xing +12
A series of LiFeCoAs compounds with different Co concentrations have been studied by transport, optical spectroscopy, angle-resolved photoemission spectroscopy and nu…
ARPES measurements of the superconducting gap of Fe-based superconductors and their implications to the pairing mechanism
P. Richard, T. Qian, H. Ding
Its direct momentum sensitivity confers to angle-resolved photoemission spectroscopy (ARPES) a unique perspective in investigating the superconducting gap of multi-band systems. In…
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…

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…
