Is Graphene the New Silicon?

Electrons travel through extremely thin form of graphite with little resistivity

Optical microscope image of the graphene device.

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.
