(a-c) LEEM image sequence of the CVD growth of graphene on top of the Co(100) film at a sample temperature of 800 K while backfilling the experimental chamber with ethylene; (d) C 1s core level for the graphene-covered (top) and uncovered regions (bottom), along with the fit. Corresponding XPEEM images of the total (e), graphitic (f) and carbidic (g) carbon. The images were acquired at the peaks indicated by the colored lines on the top spectrum in (d). Angle resolved photoemission-derived energy vs. momentum maps of the C/Co substrate (h) and graphene-covered one (i). 0 2 4 6 8 Binding energy (eV) -2 -1 0 1 2 C/Co Gr/C/Co -1 k (Å ) II π π’ max min b c 620 s 1270 s 0 s 1 μm Co(1x1) C-Co Data Fit Surface C Interacting Gr Decoupled Gr Dissolved C 286 284 282 Binding energy (eV) Intensity (arbitrary units) Gr/C/Co C/Co C 1s C 1s carb C 1s Gr C 1s tot 1 μm b 0 2 4 6 8 Binding energy (eV) a da e f g h i Surfaces and Interfaces Elettra Highlights 2024–2025 127
