ABSTRACT
The randomness of dopant atom distributions in cuprate high-critical temperature superconductors has long been suspected to cause nanoscale electronic disorder. In the superconductor Bi2Sr2CaCu2O8+delta, we identified populations atomic-scale impurity states whose spatial densities follow closely those oxygen atoms. We found that impurity-state locations are strongly correlated with all manifestations This disorder occurs via an unanticipated mechanism exhibiting high-energy spectral weight shifts, associated strong superconducting coherence peak suppression but very weak scattering low-energy quasi-particles.
