Physicochemical interactions at Cu-MgO buried interfaces are studied by electron X-ray emission spectroscopy and compared to results obtained for native interfaces. The atomic arrangement is also determined. The role of the characteristics of the substrate is evidenced. Results suggest that weak or strong interactions can be present at the interfaces.
