Abstract

We have performed angle resolved photoelectron spectroscopy (ARPES) on the electron doped cuprate superconductor Nd_1.85Ce_0.15CuO₄. We find a linear dependence of the peak width (scattering rate) on the binding energy along the zone diagonal, which is in contrary to one's naive Fermi liquid expectation. In addition, two components with very different momentum dependences are seen in the near E_f spectral function. This contrasts strongly with the hole doped materials.
