Figure 4: In situ imaging of the compression of Cu–graphene multilayers.
From: Strengthening effect of single-atomic-layer graphene in metal–graphene nanolayered composites
TEM images of a Cu–graphene nanopillar with a single layer of graphene (a) before and (b) after compression testing showing the effectiveness of graphene in blocking gliding dislocations from propagating to the next layer. Scale bar, 100 nm.
