Abstract

Graphene is a single layer of graphite. Graphene is expected to exhibit the relativistic Josephson effects, when ballistic transport is realized in it. Here, we report a method to fabricate ultrashort graphene Josephson junctions with length as short as several tens of nm, which is much shorter than the estimated mean free path of the graphene film after the junction fabrication processes.
