Identification of Nodal Kink in Electron-Doped (Nd1.85Ce0.15)CuO4 Superconductor from Laser-Based Angle-Resolved Photoemission Spectroscopy

Identification of Nodal Kink in Electron-Doped (Nd1.85Ce0.15)CuO4 Superconductor from Laser-Based Angle-Resolved Photoemission Spectroscopy

High-resolution laser-based angle-resolved photoemission measurements have been carried out on the electron-doped (Nd1.85Ce0.15)CuO4 high temperature superconductor. We have revealed a clear kink at ~60 meV in the dispersion along the (0,0)–(π,π) nodal direction, accompanied by a peak-dip-hump featu...
