[Auszug] In the prototypical hole-doped superconductor system La2_xSrxCuO4, each Cu atom is surrounded by a tetragonally distorted octahedron of O atoms. In the undoped compound, each Cu ion is in a 3d9 configuration (2+ valence), whereas the 2p states of the oxygen atoms are fully occupied. When Sr2+ is ...
