Band dependent inter-layer -electron hybridization in CeRhIn
Q. Y. Chen, D. F. Xu, X. H. Niu +16
A key issue in heavy fermion research is how subtle changes in the hybridization between the 4 (5) and conduction electrons can result in fundamentally different ground state…
Electronic structure of FeS
J. Miao, X. H. Niu, D. F. Xu +11
Here we report the electronic structure of FeS, a recently identified iron-based superconductor. Our high-resolution angle-resolved photoemission spectroscopy studies show two hole…
Direct observation of how the heavy fermion state develops in CeCoIn5
Q. Y. Chen, D. F. Xu, X. H. Niu +19
Heavy fermion materials gain high electronic masses and expand Fermi surfaces when the high-temperature localized f electrons become itinerant and hybridize with the conduction ban…
Bulk and surface electronic structure of trigonal structured PtBi2 studied by angle-resolved photoemission spectroscopy
Q. Yao, Y. P. Du, X. J. Yang +12
PtBi2 with a layered trigonal crystal structure was recently reported to exhibit an unconventional large linear magnetoresistance, while the mechanism involved is still elusive. Us…
Presence of Exotic Electronic Surface States in LaBi and LaSb
X. H. Niu, D. F. Xu, Y. H. Bai +7
Extremely high magnetoresistance (XMR) in the lanthanum monopnictides La ( = Sb, Bi) has recently attracted interest in these compounds as candidate topological materials. Ho…
Temperature-induced band selective localization and coherent-incoherent crossover in single-layer FeSe/Nb:BaTiO3 /KTaO3
Y. J. Pu, Z. C. Huang, H. C. Xu +5
Iron chalcogenide superconductors are multi-band systems with strong electron correlations. Here we use angle-resolved photoemission spectroscopy to study band dependent correlatio…
Highly anisotropic and two-fold symmetric superconducting gap in nematically ordered FeSeS
H. C. Xu, X. H. Niu, D. F. Xu +7
FeSe exhibits a novel ground state in which superconductivity coexists with a nematic order in the absence of any long-range magnetic order. Here we report an angle-resolved photoe…
