摘要: The 2p 6d feature in the Bi L3 spectra has different energies semiconducting (0.0≤x<0.7) and superconducting (x=0.75) compositions of BaBi1−xPbxO3. Bi 4f core level spectrum shows distinct features ascribable to Bi III V BaBiO3 compositions; width 4f peaks is also considerably larger these compared that BaBi0.25Pb0.75O3, which a single sharp feature.
