The ESEM image (a) shows a complex shaped multi-layer graphene. The brightness in the secondary electron image changes with each additional layer. (b) Reproduced the shape of multi-layer graphene using GSs coalescence, and (c) is a zoom-in of local brightness topography over the region indicated by the yellow window in panel (b). (d) Schematic representation of initial state (c) using origami-kirigami like graphene folds. The number of layers can be abstracted by comparing the contrast in the images with the contrast legend in the (a,b). According layout of graphene folding in (c), the coalescence of GSs are simulated by KMC in (e–h) and represent apparent layer-by-layer growth behaviour.
