Abstract

The O1s core level spectra recorded for the Bi₂Sr₂Ca_n-1Cu_nO_2n+2+δ (n = 1, 2, and 3) oxides are investigated by taking into account the layered structures, the well developed cleavage between double Bi-O layers, and the surface sensitivity of photoelectron spectroscopy. The results show that the O1s core lines with binding energies of 527.9, 528.7, and 529.4 eV can be attributed to oxygen atoms in the Cu-O₂, Bi-O, and Sr-O layers, respectively. In the Bi₂Sr₂Ca_1-xY_xCu₂O_y system, the O1s line corresponding to oxygen atoms in the Cu-O₂ planes shifts significantly to the high binding energy side with the substitution of Y for Ca. These results are discussed in terms of hole concentrations of metal-oxygen bonds.
