Angle-resolved photoemission spectroscopy of electron-doped cuprate superconductors: Isotropic electron-phonon coupling
Seung Ryong Park, D. J. Song, C. S. Leem +4
We have performed high resolution angle resolved photoemission (ARPES) studies on electron doped cuprate superconductors Sm2-xCexCuO4 (x=0.10, 0.15, 0.18), Nd2-xCexCuO4 (x=0.15) an…

Electron Removal Self Energy and its application to Ca2CuO2Cl2
Chul Kim, S. R. Park, C. S. Leem +5
We propose using the self energy defined for the electron removal Green's function. Starting from the electron removal Green's function, we obtained expressions for the removal sel…

Electronic Structure of Electron-doped Sm1.86Ce0.14CuO4: Strong `Pseudo-Gap' Effects, Nodeless Gap and Signatures of Short Range Order
S. R. Park, Y. S. Roh, Y. K. Yoon +7
Angle resolved photoemission (ARPES) data from the electron doped cuprate superconductor SmCeCuO shows a much stronger pseudo-gap or "hot-spot" effect than th…
