| Popis: | We have investigated the incident polarization dependence of the Co L 3 soft X-ray emission spectra for the single- and double-atomic height Co islands grown on the nitrogen-adsorbed Cu(0 0 1) surface. For non-resonant incident X-ray in the depolarized configuration, a shoulder structure appeared at the high-energy side of the main peak of the spectra while there is no shoulder in the polarized configuration. The shoulder is attributed to the excitation of correlation satellite originated from the periphery Co atoms of the Co nano-islands. The resonant X-ray emission spectrum in the polarized configuration with the excitation energy of the L 3 absorption peak shows a peak located at the high-energy side of the main peak. This additional peak was not observed in the depolarized configuration. |
