A method for fabricating graphene nanoribbons comprises the steps of providing a chamber with a first and a second cavity, which are separated by a divider that defines an opening to place the first cavity in fluid communication with the second cavity; positioning a graphite sample in the first cavity; positioning a container with a metal disposed therein in the second cavity; heating the container to expel a cloud of metal; injecting a gas into the second cavity to propel the cloud of metal through the opening and into the first cavity where it contacts the graphite sample to produce dislocation bands; removing the graphite sample from the chamber; and electrostatically depositing the dislocation bands on a substrate as graphene nanoribbons.

Methods and systems for fabrication of graphene nanoribbons

A method for electrostatic deposition of graphene on a substrate comprises the steps of securing a graphite sample to a first electrode; electrically connecting the first electrode to a positive terminal of a power source; electrically connecting a second electrode to a ground terminal of the power source; placing the substrate over the second electrode; and using the power source to apply a voltage, such that graphene is removed from the graphite sample and deposited on the substrate.
