Making contact: Researchers wire up individual graphene nanoribbons

Researchers have developed a method of ‘wiring up’ graphene nanoribbons (GNRs), a class of one-dimensional materials that are of interest in the scaling of microelectronic devices. Using a direct-write scanning tunneling microscopy (STM) based process, the nanometer-scale metal contacts were fabricated on individual GNRs and could control the electronic character of the GNRs. The researchers say that this is the first demonstration of making metal contacts to specific GNRs with certainty and that those contacts induce device functionality needed for transistor function.
