Comparison of Cu Auger electron transitions between the superconductor YBa2Cu3O7-x and the oxides of Cu—O system
Overview & Synopsis
Auger electron spectroscopy (A.E.S.) has been employed to investigate the valence of copper in superconducting YBa2Cu3O7-x ceramics. Comparison of A.E.S. spectra of YBa2Cu3O7-x with CuO and Cu2O oxides shows a very specific LM45M45 electronic transition for copper in the superconductor. A very clear doublet splitting of the L 3M45M45 transition is observed in YBa2Cu3O7-x. This result can be attributed approximately to the existence of two valency states Cu+ and Cu2+ for copper. Another interpretation could be to consider the existence of a strong splitting in the 3d orbital level of copper.
