• from impurities collected through the sample transfer. Due to the high symmetry of the Zn 2p3/2 peak, analysis of the Auger parameter α was needed to understand the electronic structure of the layer (Figure 3c). Figure 3d shows the Zn 3d region, including an inset with the depth dependence of the ZnO

• interfacial energy levels of oxidized Zn was obtained from comparing the kinetic energy Ekin(jkl) of the main Auger transition jkl, here Zn LMM, with the binding energy EB(i) of a photoelectron from the main atomic level i, here Zn 2p [44][45] as The Auger parameter α is a measure in the differences in

• change of the modified Auger parameter α’ is monitored according to Δα’ = ΔEB(XPS) + ΔEkin(XAES) (Ekin corresponds to the kinetic energy). On the other hand, the modified Auger parameter α’ is correlated to the dynamical or one-hole relaxation energy RD (Δα´≈ 2·ΔRD) and thus to the electronic

• state [5][19]. On the other hand, in case of fluorinated Pcs the absence of a local charge transfer process at the fluorine atom allows the estimation of the polarization screening via the corresponding Auger parameter [19].
