modified. Says Crommie, “The optimist says, ‘Wow, look at all the ways we can control these states – this might allow a whole new technology!’ The pessimist says, ‘Uh-oh, look at all the things that can disturb a nanoribbon’s behavior – how are we ever going to achieve reproducibility on the atomic scale?’”

Crommie himself declares that “meeting this challen- ge is a big reason for why we do research. Nanorib- bons have the potential to form exciting new electro- nic, magnetic, and optical devices at the nanoscale. We might imagine photovoltaic applications, where absorbed light leads to useful charge separation at nanoribbon edges. We might also imagine spintro- nics applications, where using a side-gate geometry would allow control of the spin polarization of elec- trons at a nanoribbon’s edge.” Although getting there won’t be simple – “The edges have to be controlled,” Crommie emphasizes – “what we’ve shown is that

it’s possible to make nanoribbons with good edges and that they do, indeed, have characteristic edge states similar to what theorists had expected. This opens a whole new area of future research involving the control and characterization of graphene edges in different nanoscale geometries.”
