Fig. 1: Characterization of Cu (111) and grown BLG.
From: Specific stacking angles of bilayer graphene grown on atomic-flat and -stepped Cu surfaces
a XRD pattern of Cu (111). b EBSD mapping image of Cu (111). The inset is the color coding orientation triangle. The blue color region is (111) plane, and the pink color region is (311) plane. c SEM image of BLG/Cu (111). BLGs grown on Cu (111) have AB-stacking or 30°-twisted stacking order. The stacking angle is determined by dashed lines. AB-stacked BLG (blue dashed line) has 0° of stacking angle. 30°-twisted BLG (red dashed lines) has 30° of stacking angle. d Stacking angle distribution of BLG grown on Cu (111).
