"Graphene, a one-atom-thick layer of graphite where carbon atoms are held in a hexagonal lattice reminiscent of chicken wire, has some unusual properties, one of which may allow it to replace silicon in high-speed electronics. At room temperature, graphene exhibits extremely high electron mobility—the speed at which electrons move through the material is over 100 times greater than silicon. However, because its material properties are different from traditional semiconductors, researchers have struggled to develop integrated circuits with graphene components. Now, a paper in last week's Science demonstrates graphene integrated circuitry printed on silicon wafers."
