The Nematic Energy Scale and the Missing Electron Pocket in FeSe
Ming Yi, Heike Pfau, Yan Zhang +12
Superconductivity emerges in proximity to a nematic phase in most iron-based superconductors. It is therefore important to understand the impact of nematicity on the electronic str…
Band structure reconstruction across nematic order in high quality FeSe single crystal as revealed by optical spectroscopy study
Haipeng Wang, Zirong Ye, Yan Zhang +1
We perform an in-plane optical spectroscopy measurement on high quality FeSe single crystals grown by a vapor transport technique. Below the structural transition at $T_{\rm s}\sim…
Photoemission study of the electronic structure and charge density waves of Na2Ti2Sb2O
S. Y. Tan, J. Jiang, Z. R. Ye +7
The electronic structure of Na2Ti2Sb2O, a parent compound of the newly discovered titanium-based oxypnictide superconductors, is studied by photon energy and polarization dependent…
Anomalous phonon redshift in K-doped BaFe2As2 iron pnictides
B. Xu, Y. M. Dai, B. Shen +9
The effect of K, Co and P dopings on the lattice dynamics in the BaFeAs system is studied by infrared spectroscopy. We focus on the phonon at 253 cm, the high…
Anisotropic but nodeless superconducting gap in the presence of spin density wave in iron-pnictide superconductor NaFe1-xCoxAs
Q. Q. Ge, Z. R. Ye, M. Xu +7
The coexisting regime of spin density wave (SDW) and superconductivity in the iron pnictides represents a novel ground state. We have performed high resolution angle-resolved photo…
Heavily electron-doped electronic structure and isotropic superconducting gap in AxFe2Se2 (A=K,Cs)
Y. Zhang, L. X. Yang, M. Xu +10
The low energy band structure and Fermi surface of the newly discovered superconductor, AxFe2Se2 (A=K,Cs), have been studied by angle-resolved photoemission spectroscopy. Compared…
