Abstract/OtherAbstract:
An approach to fabricate large-scale graphene nanoribbons (GNRs) with tunable ribbon widths is presented. Regular steps with variable heights from 1 to 100 nm can be prepared on a SiC substrate by a low-pressure etching process. Graphene can be epitaxially grown only on the side walls of the steps, thereby leading to GNRs with controllable widths.
