Description
Samples with the nominal composition Bi2Sr2Ca1Cu2-xNixO8+δ (x = 0.00, 0.02, 0.10, 0.20) have been studied by X-ray photoelectron spectroscopy (XPS). From deconvolution of Bi 4f and O 1s XPS core-level spectra, we propose that the main reason leading to the decrease of superconducting transition temperature (Tc) with increasing Ni content, is the distortion of the Bi-2212 crystal structure by extra oxygen being intercalated between the adjacent Bi-O layers which then affects the hole concentration (nh) of the CuO2 planes.
