N2 - Using angle-resolved photoemission and linearly polarized synchrotron radiation, we measured the electronic band structure of electronic states of CuO(Formula presented) plane materials ranging from insulators (Sr(Formula presented) to overdoped superconductors (Bi(Formula presented). We report three results: (i) The CuO(Formula presented) containing insulator possesses a spin-density-wave (SDW) ground state; (ii) there are precursors of the SDW state for underdoped Bi(Formula presented) (iii) an extended saddle-point-type van Hove singularity is neither a necessary nor a sufficient condition for a high superconducting transition temperature, (Formula presented).
