The color part of the image is an actual color optical micrograph of a graphene device used in the study. The yellow parts are gold electrodes, the slightly darker purple area is the graphene, and the lighter purple is the substrate material (SiO2/Si). The graphene lattice, rendered by an artist, above the device represents a blown-up portion of the graphene material, in which electrons travel more than 100 times faster than silicon.
