Nano-graphene ribbons are promising in many electronic applications, as their bandgaps can be opened by reducing the widths, e.g.below 20nm. However, a high-throughput method to pattern large-area nano-graphene features is still not available. Here we report a fabrication method of sub-20nm ribbons on graphite stamps by nanoimprint lithography and a transfer-printing of the graphene ribbons to a Si wafer using electrostatic force assisted bonding. These methods provide a path for fast and high-throughput nano-graphene device production.
