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.

Armchair-type graphene nanoribbons, which are promising type of nanoribbon for device application, display width-dependent band gap. They can be classified into three subfamilies (3p, 3p + 1, 3p ...

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 ...

Researchers report the systematic investigation of the effects of oxygen on the synthesis of 3p sub-family armchair graphene nanoribbons (3p-AGNRs), which revealed a strong catalytic effect with a ...

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 ...

(PhysOrg.com) -- As far back as the 1990s, long before anyone had actually isolated graphene – a honeycomb lattice of carbon just one atom thick ... For nanoribbons with an armchair edge, ...

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 ...
