Figure 8: Different types of bubbles and comparing with bulks.
From: Dependence of the shape of graphene nanobubbles on trapped substance
The RDF of trapped and bulk (a) helium (b) water (c) ethanol subjected to the same amount of pressure at room temperature (see Table 1). Each inset shows top and side views of corresponding trapped substances. The cyan and red balls represent the two different layers (graphene top layer and the graphene substrate are not shown here).
