| Abstract: | The electronic structure of (LaSr)2CuO4 and (NdCe)2CuO4 are compared. It is concluded that in both materials after doping by holes and electrons respectively the Fermi energy is at the top of the valence band. This explains many symmetrical properties and in particular the photoemission experiments.Dedicated to Prof. P. Kienle on the occasion of his 60th birthday |
