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…
Evolution of a pairing-induced pseudogap from the superconducting gap of (Bi,Pb)2Sr2CuO6
K. Nakayama, T. Sato, Y. Sekiba +7
We have performed an ultrahigh-resolution angle-resolved photoemission spectroscopy study of slightly-overdoped (Bi,Pb)2Sr2CuO6 to elucidate the origin of pseudogap. By using a new…
Electronic structure of heavily electron-doped BaFeCoAs studied by angle-resolved photoemission
Y. Sekiba, T. Sato, K. Nakayama +9
We have performed high-resolution angle-resolved photoemission spectroscopy on heavily electron-doped non-superconducting (SC) BaFeCoAs. We find that the two ho…
Fermi surface nesting induced strong pairing in iron-based superconductors
K. Terashima, Y. Sekiba, J. H. Bowen +10
The discovery of high-temperature superconductivity in iron pnictides raised the possibility of an unconventional superconducting mechanism in multiband materials. The observation…
Superconducting gap symmetry of Ba0.6K0.4Fe2As2 studied by angle-resolved photoemission spectroscopy
K. Nakayama, T. Sato, P. Richard +8
We have performed high-resolution angle-resolved photoemission spectroscopy on the optimally-doped BaKFeAs compound and determined the accurate momentum dep…
Band Structure and Fermi Surface of an Extremely Overdoped Iron-Based Superconductor KFe2As2
T. Sato, K. Nakayama, Y. Sekiba +8
We have performed high-resolution angle-resolved photoemission spectroscopy on heavily overdoped KFe_2As_2 (transition temperature (Tc = 3 K). We observed several renormalized band…
