Graphene semiconductor theory confirmed
Abstract:
Graphene, sheets of pure carbon atoms akin to unrolled nanotubes laid flat, could herald a new era of ultra-high speed semiconductors. But the precise topology required to make them has yet to be verified experimentally.
Now, the gap between theory and experimental observations has been bridged, according to an electrical engineering professor at the University of Illinois.
The theory stated that nanoribbons of graphene measuring less than 10-nanometers wide could serve as ultra-fast channels for transistors, but they needed to be cut across the grain of the hexagonal lattice of carbon atoms. Nanoribbons cut with the grain, resulting in a zig-zag pattern at their edges, could serve as good metallic interconnections, but theorists predicted that only so-called "armchair" nanoribbons would make good semiconductors.
Professor Joseph Lyding and co-researcher Kyle Ritter at Micron Technology Inc. (Boise, Idaho) claim to have validated the theory.
