Surface core-level shifts of clean and oxygen-covered Ru(0001)

Surface Core - Level Shifts at an oxygen - rich Ru Surface :

We present density-functional theory calculations of Ru 3d and O 1s surface core-level shifts (SCLSs) at an oxygen-rich Ru(0001) surface, namely for the O(1× 1)/Ru(0001) chemisorption phase and for two surface terminations of fully oxidized RuO2(110). Including final-state effects, the computed SCLSs can be employed for the analysis of experimental X-ray photoelectron spectroscopy (XPS) data en...

Non-local Effects on Oxygen-Induced Surface Core Level Shifts of Re(0001)

The electronic structure of clean and oxygencovered Re(0001) was investigated by combining high energy resolution core level photoelectron spectroscopy and density functional theory. For the clean surface, we detect two distinct Re 4f7/2 components shifted by 95 meV, which we ascribe to photoemission from the bulk and the top layer of the crystal. Oxygen adsorption at room temperature leads to ...
