Figure 3: Mapping doped regions and corrugations of graphene.
From: Imaging local electronic corrugations and doped regions in graphene
False colour images displaying (a) π*at 285.5 eV and (b) pre-edge at 283.7 eV, where each image shows prominent C K-edge resonances. Colour scales on the left represent absolute OD values, and to the right reflect the normalized OD, referenced to the carbon signal at 320 eV. The scale bar corresponds to 1 μm with a total distance across the image of 4 μm. The pre-edge peak is prominent in (c), where only high (red–yellow) OD regions in (b) were selected for the spectrum.
