Fig. 2: Synthesis and characterizations of H-type GPG.
From: Van-der-Waals-forces-modulated graphene-P-phenyl-graphene carbon allotropes
a The schematic for layer-by-layer synthesis of GPG from high quality CVD graphene; b The 3D and (c) detailed side view CHGDIFF of GPG between the layers; d ACTEM image of GPG top view; e AFM image of GPG top view; f The hight profile for single/double-layer GPG edge (grey ball are carbon atoms); g TEM image of GPG; h Enlarged TEM and ACTEM (inserted) images of GPG; i ACTEM image and modelling structure of the top view for H-type GPG: the original ACTEM image (top left); the theoretical model of of H-type GPG (top right); the alignment of ACTEM image and theoretical model of H-type GPG (bottom); j Side view of the modelling structure of H-type GPG (The grey sticks represent C–C bonds. All balls denote carbon atoms, with the pink and purple ones corresponding to the same set of carbon atoms in the top view (i) and side view (j), respectively. The ball-shaped atoms are those visible in the top view and are highlighted accordingly).
