Graphene can be transformed from a semimetal into a semiconductor if it is confined into nanoribbons narrower than 10 nm with controlled crystallographic orientation and well-defined armchair edges.

Researchers may give science and industry a new way to manipulate graphene, which naturally rips along armchair and zigzag paths. Research from Rice University and the University of California at ...

"Interestingly, the electronic and magnetic properties of graphene nanoribbons are widely tuned as a function of the width and edge structure." says Prof. Hiroko Yamada at NAIST. Armchair-type ...

On-surface synthesis has received great attention as a method to create atomically-precise one-dimensional (1D) and two-dimensional (2D) polymers with intriguing properties. In particular ...

Armchair graphene nanoribbons The paper "Quantum electronic transport across "bite" defects in graphene nanoribbons," recently published in 2D Materials, specifically looks at 9-atom wide armchair ...

Progressively zoomed-in images of graphene nanoribbons grown on germanium. The ribbons automatically align perpendicularly and naturally grow with their edges oriented along the carbon-carbon bond ...

We determined the structure of ~100 folded graphene edges by electron nanodiffraction. About 1/3 are armchair and 1/3 are zigzag. The results are explained by the energetics of graphene folding and ...

a 12-sp-atom chain bridging two GNRs with armchair edges. The unit for bond length is Å. Physics Letters has an article on carbon atomic chains being produced from graphene. Stable and rigid carbon ...
