(a) The second derivative with respect to the energy of the photoemission intensity around the Brillouin zone center for 35 uc Co-doped FeSe/STO. (b) The photoemission spectra around the Brillouin zone corner. (c) Photoemission intensity map at Fermi energy, which is integrated over ( E _F + 10 meV, E _F − 10 meV). (d) The symmetrized EDCs around the Fermi momentum of the electron pocket around the Brillouin zone corner at 30 K. Panels (a)–(d) are reprinted with permission from Ref.
