Although the crystal structures of the copper oxide high-temperature superconductors are complex and diverse, they all contain some crystal planes consisting of only copper and oxygen atoms in a square lattice: superconductivity is believed to originate from strongly interacting electrons in these CuO2 planes. Substituting a single impurity atom for a copper atom strongly perturbs the surrounding electronic environment and can therefore be used to probe high-temperature superconductivity at the… 
Interplay of magnetism and high-Tc superconductivity at individual Ni impurity atoms in Bi2Sr2CaCu2O8+δ
TLDR
Scanning tunnelling microscopy is used to determine directly the influence of individual Ni atoms on the local electronic structure of Bi2Sr2CaCu2O8+δ and shows that quasiparticle scattering at Ni is predominantly non-magnetic, consistent with predictions for impurity atom phenomena derived from a magnetic mechanism.
Microscopic electronic inhomogeneity in the high-Tc superconductor Bi2Sr2CaCu2O8+x
TLDR
The presence of an electronic inhomogeneity is reported in Bi2Sr2CaCu2O8+x, a consequence of proximity to a Mott insulator resulting in poor screening of the charge potentials associated with the oxygen ions left in the BiO plane after doping, and is indicative of the local nature of the superconducting state.
Microscopic hamiltonian for Zn- or Ni-substituted high-temperature cuprate superconductors
We have derived the effective low-energy Hamiltonian for Zn- or Ni-substituted high-T-c cuprates from microscopic three-band models consisting of the most relevant Cu or impurity 3d and O 2p

Dopant structural distortions in high-temperature superconductors: anactive or a passive role?
TLDR
Results are presented here on (Sr, Ba) and Ni dopants, which substitute at the La and Cu sites, respectively, of insulating La2CuO4, and the relevance of the measured local distortions for a complete understanding of the normal and superconducting properties of cuprates is discussed.
Imaging the Impact of Single Oxygen Atoms on Superconducting Bi2+ySr2–yCaCu2O8+x
TLDR
It is shown that the nanoscale spatial variations in the pseudogap states are correlated with disorder in these dopant concentrations, particularly that of apical oxygen vacancies, and this range is extended to reveal the positions of the remaining oxygen defects in Bi2+ySr2-yCaCu2O8+x.
Merohedral disorder and impurity impacts on superconductivity of fullerenes

Mapping the orbital structure of impurity bound states in a superconductor
TLDR
Density functional theory simulations correlate the orbital shapes to the magnetic ground state of the atom, and identify scattering channels and interactions, all valuable tools for designing atomic-scale superconducting devices.
Impurity effects on electron–mode coupling in high-temperature superconductors
Despite years of intensive research on copper oxide superconductors with high transition temperatures (Tc), the driving force of superconductivity has not yet been clarified. Angle-resolved

TLDR
It is shown that the electronic structure of pristine Mott insulator is consistent with the Zhang-Rice singlet model, but the peculiar features of the doped electronic states require further investigations.

Atomic-scale quasi-particle scattering resonances in Bi2Sr2CaCu2O8+delta
TLDR
Low-temperature scanning tunneling spectroscopy of the high transition temperature (high-Tc) cuprate Bi2Sr2CaCu2O8+delta reveals the existence of large numbers of identical regions with diameters of about 3 nanometers that have a relatively high density of low-energy quasi-particle states, consistent with theories of strong quasi- particle scattering from atomic-scale impurities in a d-wave superconductor.
