文摘

The doping dependence of the electron spectral function of the electron doped cuprate superconductors is studied within the framework of the kinetic energy driven superconductivity. It is shown that with increasing the electron doping concentration, the weight of the superconducting quasiparticle peak at the [π, 0] point increases, and the position of the peak is shifted toward to the Fermi energy.
