Abstract

Graphene nanoribbons: a slice of the action Graphene, made up of graphite sheets a single atom thick, is an electronic conductor. However thin strips of the material, called graphite nanoribbons or GNRs, can express different electronic properties depending on their width. This tunability could lead them to overtake nanotubes for some applications. Producing bulk quantities of ribbons in a scalable manner has been a challenge until now, but it is required for using them in electronics applications. A team from Stanford University team now report an approach to reliably produce sub-10-nm graphene nanoribbons by partial encapsulation of carbon nanotubes in a polymer. A longitudinal strip of the nanotube remains exposed and can be cut by plasma etching, resulting in the unzipping of the nanotube when the polymer is removed, and formation of a thin strip of graphene. The potential of the material was demonstrated by using it to produce effective field-effect transistors.
