The catalytic reduction of NO by H2 on Ru(0001): Observation of NHads species

“…The concentrations of the chemical elements in the near-surface region were estimated after the subtraction of a Shirley type background, taking into account the corresponding atomic sensitivity factors [28]. The surface concentrations of the oxygen-containing species (NO ads and O ads ) were estimated by measuring the ratio between the areas of the O 1s and Ru 3d 5/2 peaks.…”

Electronic structure of YbGa1.15Si0.85and YbGaYamaoka1, Jarrige2, Tsujii3 et al. 2011Phys. Rev. B

“…This could be explained because as the energy goes to 9 eV from 35 eV, the 4f photoionization cross-section decreases, while those of Ga 4p, Ge 4p and Si 3p increase in a log-scale. 41 The Kondo resonance peak at the Fermi edge appears as a result of the hybridization, i. e. in a mixed valence system the Yb 2+ 4f 7/2 peak is located at ǫ F if the hybridization is strong. 42 band spectra of YbGa x Si 2−x and YbGa x Ge 2−x the 4f 7/2 peak is away from ǫ F , hence, it cannot be attributed to the Kondo resonance peak.…”

Electronic structure of epitaxial SrRuO3 films studied by resonant photoemission

“…Unfortunately, the resonance intensity is relatively low compared with CS variations. Moreover, the energy dependence of peaks A (which is mostly from the Ru 4d states) and F (CO-contamination peak, essentially O 2p in character) differs not as strongly as it might be expected from the atomic CSs hn-dependences (Plummer et al, 1977;Yeh and Lindau, 1985). Actually, we observe that upon going from 70 to 100 eV exciting photon energy (i.e.…”

“…Actually, we observe that upon going from 70 to 100 eV exciting photon energy (i.e. in the off-resonance region) the intensity ratio of peaks A and F decreases less than two times, while the corresponding decrease of the (Ru 4d)/(O 2p) atomic CSs ratio is around 6 (Yeh and Lindau, 1985). As it was discussed in the introduction, this disagreement is not surprising; however, it shows that the assumption about the mainly O 2p character of the VB spectrum at CM (Park et al, 2004a(Park et al, , 2004bFujioka et al, 1997) should be treated with caution.…”

“…A possible way to do it is to utilize the similarity in the photon energy dependence of the CSs for 2p states in oxygen and (O 2p-C 2s) orbitals in CO (Wilhelmy et al, 1994;Plummer et al, 1977;Yeh and Lindau, 1985). Such normalization to the intensity of adventitious contamination peaks around $ 10 eV binding energy (BE) from carbon monoxide in principle should provide almost flat O 2p spectral weight in this region (Park et al, 2004a(Park et al, , 2004b.…”
