What is it about?

Imprinting electrical circuits in graphene might be achieved by controlled hydrogenation. Pairs of stable hydrogen dimer-lines, recently realized in the laboratory, are shown to confine electrons and to act as electron waveguides or nanotransistors (depending on the their width) chemically imprinted in graphene.

Why is it important?

Progress in fabricating nanostructured devices with desired electronic properties may reach in the near future the atomic scale where atoms or groups of atoms act as individual components of electric circuits, provided some stability issues are overcome. Here it is shown how H atoms can be used to design atomic-scale circuits on a robust substrate, which can eventually functionalized as desired.
