Figure 5
UV-PEEM image of a monolayer of graphene on a Ge buffer layer on SiC(0001). The field of view is 25 µm × 25 µm. The red arrow in the bottom-left highlights the detector region with a thinned entrance-window as discussed in §3.2. (b) Line profiles across the long axis of the two boxes with solid and dashed lines, by averaging along the perpendicular direction (each 11 pixels wide) as shown in (a). |
