Graphene on gold pillars with height  = 60 nm and inter-pillar separation  = 500 nm. (a) Scanning electron micrograph at 60° inclined to the vertical. (b) Top view of the same region. (c) High-angle SEM image of the same region posterior to AFM scanning. The pillars A, B, and C were knocked out and pillar D was destroyed by the moving sharp tip. (d) Topography of the same region showing shadow effects due to AFM tip geometry.

FIG. 3.

SEM image of graphene on gold pillars with height  = 100 nm and inter-pillar separation  = 500 nm: Blister A is one of the many coalesced blisters in this sample. Blister B is torn on one side resulting in lateral corrugation. C is a pillar bent by the graphene from above. Region D is a cluster of nano-Au particles and pillar debris covered by an irregular shape graphene blister.
