Abstract

Low temperature scanning tunneling microscopy (STM) of various samples of the high temperature superconductor Bi2Sr2CaCu 2O8+δ consistently reveals the presence of quasi-particle scattering resonances, similar both spectro-scopically and spatially to those observed around Zn atoms in Zn-doped BSCCO. As the resonances appear at energies indicative of nearly unitary scattering (∼0.5 meV) and are always accompanied by topographic depression of the surface Bi atom around which they are centered, we postulate that the source of scattering may be Cu vacancies in the CuO2 plane. Such resonances should thus provide a simpler test case for theoretical models than those created by Zn or Ni substitution.
