ARPES intensity maps of graphene on quartz and BN.

(A–B) Normalized and raw ARPES intensity maps of graphene/quartz (panel (A)) and graphene/BN (panel (B)), respectively. The red and dark-yellow lines are the dispersions, obtained by fitting momentum distribution curves (MDCs). (C) MDCs at EF for graphene on SiC(000-1) (blue line), BN (dark-yellow line), quartz (red line) and SiO221 (gray-dashed line).
