Abstract

High-resolution, low-temperature scanning tunneling microscopy and spectroscopy on Bi₂Sr₂CaCu₂O_8+δ reveal the existence of large numbers of scattering centers in this material. The spatial and spectroscopic characteristics of these features are consistent with theories of quasiparticle scattering from atomic scale impurities in a d-wave superconductor. These characteristics include breaking of local particle-hole symmetry and an inverse square dependence of their local density-of-states (LDOS) on distance from the scattering center. Furthermore, these observations identify a source for the anomalously high levels of low-energy excitations in Bi₂Sr₂CaCu₂O_8+δ at low-temperatures.
