Figure 4
Spatially and angularly resolved photoelectron intensity distribution maps of HOPG. The 200 µm × 200 µm image (a) was acquired by the analyzer in SA mode (1.4°) in the [−0.1 to +1.9] eV binding-energy window with respect to EF. The azimuth of the acquisition direction is shown by the thick white arrow and the polar direction was close to 41.6°, the ΓK radius in the first Brillouin zone (FBZ). In the inset, the colour scale of (a) is drawn in the FBZ of graphite showing possible variations in the orientation of the flakes with corresponding colour code along the KMK directions. The energy window for the image (a) is shown by the red line on band dispersion curves in momentum space obtained from the polar angle scans along the ΓK (b) and ΓM (c) directions from point A of the image.
