Graphene edges closer to atomically precise nanotechnology

Two papers in a recent issue of Science suggest that graphene is rapidly moving from being “just” a nanotech wonder material to becoming relevant to atomically precise nanotechnologies.

STM brings near-atomic resolution to graphene nanotechnology

The recent demonstration of the ability to “fully engineer the electronic band gap of graphene” is a major advance in the top-down approach to nanotech applications that take advantage of the many marvelous properties of graphene.

Toward atomically precise graphene structures for nanotechnology

Researchers have demonstrated atomically precise cuts through a few graphene layers.

Nanotechnology demonstration of room-temperature graphene transistors

In yet another step toward making nanotech transistors from graphene nanoribbons, chemically-prepared graphene nanoribbons less than 10 nm wide were found to be uniformly room-temperature, field-effect transistors.
