The researchers' membrane, consisting of graphene on a polycarbonate track etch membrane (the graphene is the darker region in the center of the white film). The total membrane is about 2 cm wide by 1 cm tall, while the graphene portion is about 5 mm by 5 mm.

A high-resolution scanning transmission electron microscope image taken at Oak Ridge National Laboratory showing a large hole in the graphene (black region in the center). The image is 32 nm by 32 nm, hence the hole is about 10 nm in diameter. The white on the surface of the graphene is contamination, which is a recurring problem for anyone imaging graphene using this technique.

Another high-resolution scanning transmission electron microscope image taken at Oak Ridge National Laboratory showing a small hole in the graphene (small black region slightly below the center). The image is 8 nm by 8 nm, meaning that the hole is 0.5 nm in diameter. In this image the honeycomb structure of graphene lattice is clearly seen.
