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.

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 ...

"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 ...

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 ...

Suspended graphene in liquids folds freely under random ultrasonic stimulations. We determined the structure of ~100 folded graphene edges by electron nanodiffraction. About 1/3 are armchair and 1/3 ...

Despite being just a single layer of carbon atoms, graphene sure can excite engineers and scientists. Unlike bulk graphite, the ultrathin material boasts flexibility, strength, and possibly ...

It is no exaggeration to say that graphene, the substance that the two scientists – along with others – discovered in 2004, is a miracle material. Now a Korean research lab may have made the ...
