Fig. 4: Stacking angle-relative energy graph of BLG depending on stacking angle.
From: Specific stacking angles of bilayer graphene grown on atomic-flat and -stepped Cu surfaces
a BLG on Cu (311) and b BLG on Cu (110). Insets are the illustration for the cross-section of each crystal plane. The atomic-stepped surface morphology of (311) and (110) is displayed by pink and cyan lines, respectively.
