a Doping dependence of the symmetrized energy-momentum cuts taken around the Γ point. E−EF represents the binding energy of electrons. E is the kinetic energy of electrons and EF is the Fermi energy. k// is the in-plane momentum of electrons. b Doping dependence of the symmetrized energy distribution curves (EDCs) taken at the Fermi crossing (kF) of the α hole band. Panels c and d are the same as a and b but taken around the Μ point. The EDCs are taken at the kF of the δ electron band. The deposition sequence is denoted using Dn (n is the doping times).
