Abstract: | La0.8 – xCexSr0.2MnO3 (x= 0–0.3) mixed-conducting manganites are studied by x-ray photoelectron spectroscopy. The effect of A-site Ce substitution on the surface composition of the samples, charge states of the constituent cations, and bonding configuration is analyzed. The binding energies of the constituent elements are determined. The spectral shapes of the O 1s, La 4d, La 3d, Sr 3d, Mn 2p, Ce 4d, and Ce 3d peaks are examined as a function of Ce content. |
