Abrupt change in the energy gap of superconducting Ba1−�K�Fe2As2 single crystals with hole doping
We performed a laser angle-resolved photoemission spectroscopy (ARPES) study on a wide doping range of Ba1−KFe2As2 (BaK) and precisely determined the doping evolution of the superconducting gaps in this compound. The gap size of the outer hole Fermi-surface (FS) sheet around the Brillouin zone (BZ)...
