  • Ru 3d metallic photoemission spectrum fitted. The data were published by Kaga et al. (accession #0041702). The film was deposited on a glass substrate by reactive sputtering. A signal from oxygen was detected in the sample, but the area is too small to be associated with any of the Ru 3d peaks and a Ru oxide (under the MultiLayer Method, considering the formation of a top ruthenium oxide layer, the composition of the oxide is RuO0.2), which strongly suggests that the three Ru 3d peaks are metallic components and that the oxygen signal is associated with an adventitious species. The branching ratio of the doublets was forced to be equal to the theoretically expected value (0.6901), which was taken from the Scofield tables.

  • Two more paks but better fit of the whole available spectra. The spin-orbit splitting of the plasmon wa sforced to be equal to that of the main doublet, as it is expected.

  • The splitting of the satellite is very close to that of the main peak. There are no visible plasmons. Data from Surface Science Spectra 6, 68-74 (1999) (same as above).

  • Ru 3d metallic photoemission spectrum fitted. The data were published by Kaga et al. (accession #0041702). The film was deposited on a glass substrate by reactive sputtering. The spectrum was fitted with one Double-Lorentzian asymmetric doublet and two Voigt doublets. A signal from oxygen was detected in the sample, but the area is too small to be associated with any of the Ru 3d peaks and a Ru oxide (under the MultiLayer Method, considering the formation of a top ruthenium oxide layer, the composition of the oxide is RuO0.2), which strongly suggests that the three Ru 3d peaks are metallic components and that the oxygen signal is associated with an adventitious species.
