| Abstract: | CaCu3Ti4O12 have been prepared by solid-state reaction.X-ray diffraction shows that the structure of CCTO is body center cubic with the lattice parameter of a=0.737 8 nm;X-ray photo-emission spectroscopy verified the existence of Cu3 and Ti3 ions,and O1s core-level electron spectrum includes actually two single peaks. |
