The identification of step-atoms by high resolution core level spectroscopy
We have studied the vicinal Rh(553) surface by the use of High Resolution Core Level Spectroscopy (HRCLS). We demonstrate that we are able to resolve the photo-emitted electrons from the Rh3d5/2 level originating from the step atoms with respect to those emitted from the atoms in the (111) terrace. Our study therefore shows that it is possible to obtain a core level "fingerprint" from t
