μ-ARPES measurements on epitaxial and rotated graphene regions.
Left: momentum distribution curves; hν = 40 eV. The corresponding angular distributions of photoelectrons are shown in the insets acquired at EB = 3.56 eV and EB = 2.58 eV for epitaxial and rotated graphene regions, respectively. Right: Investigated graphene area as imaged by LEEM (top, Vstart = 12 V) and by DF-XPEEM. The dark-field images were acquired positioning an aperture at the K point in the diffraction plane, at binding energies corresponding to highlighted structures in the MDC curves on the left.
