nanotimes News in Brief
AFM image (3x3 micron in size) of single-atom-thin carbon nanofabric. Notice that graphene looks just like a silk tissue thrown on a surface: it is creased with many folds, pleats and wrinkles.
Graphene flakes of different thickness (1, 2, 3, 4 and more layers). Optical photo in normal white light. Lateral size of the image is 200 microns.
Scanning electron micrograph of a fallen mesa of graphite. This is the way graphene molecules were „extracted“ from bulk graphite. To be reasonably visible in SEM, the researcher show a 10nm carbon flake (30 layer thick).
