| dc.description.abstract | High-resolution photoemission of the Sn 4d core level of Sn/Ge(111)-(3x3) resolves three main components in the line shape, which are assigned to each of the three Sn atoms that form the unit cell. The line shape found is in agreement with an initial state picture and supports that the two down atoms are inequivalent. In full agreement with these results, scanning tunnel microscopy images directly show that the two down atoms are at slightly different heights in most of the surface, giving rise to an inequivalent-down-atoms (3x3) structure. These results solve a long-standing controversy on the interpretation of the Sn 4d core-level line shape and the structure of Sn/Ge(111)-(3x3). | |

[28] The relative intensities are affected by PED effects, but the required change is larger than the observed intensity variations due to this effect [21]. [29] R. Cortés et al. (to be published). [30] Lorentzian widths may be affected by the oxidation state due to changes of the Auger decay rate [31]. However, our sensitivity is not enough to determine independent LWs for each C2, C3, and C4 doublet. [31] J. J. Paggel et al., Surf. Sci. 414, 221 (1998). [32] The residual observed around 25–26 eV is probably due to an additional defect component. [33] V. Dudr et al., Phys. Rev. B 70, 155334 (2004). [34] A. V. Melechko et al., Phys. Rev.
