Fig. 3: Comparison CLS vs asymmetry parameter.
From: The highest oxidation state observed in graphene-supported sub-nanometer iron oxide clusters
a Core level α parameters and CLS of metallic and b oxidized iron clusters as a function of their size. Circle markers refer to asymmetry parameter while square markers refer to CLS. The error bars on the core level shifts are of the order ± 0.1 eV.
