Wafer Scale Growth and Characterization of Edge Specific Graphene Nanoribbons for Nanoelectronics

Nanoelectronics: Nanoribbons on the edge.

MIT team observed that although the ion permeability of an intact graphene membrane was negligible compared with that of a membrane that contained a nanopore, it was not zero and it was different for different cations, which indicates that electrolyte–graphene interactions need to be taken into account6. Evidence of DNA– graphene interactions was also observed6–8. These interactions will need t...

Graphene nanoribbons and edge reconstructions

Direct growth of graphene nanoribbons for large-scale device fabrication.

Graphene being a zero band gap material hinders the use of its intrinsic form for many applications requiring a moderate band gap, such as field effect transistors and optoelectronic devices. Here we demonstrate a scalable method based on chemical vapor deposition for the direct growth of well-registered graphene nanoribbons on SiO(2) substrates with precise control over their width, length, an...
