Epitaxial Graphene Quantum Electronics

Abstract

Under the NSSEFF grant, we have accomplished several of the most important experimental results in graphene to date. The epitaxial graphene route that we have pursued since 2001 has fully lived up to its expectations. As we stated in our original proposal, we hoped to duplicate the transport properties that we had observed in carbon nanotubes, 15 years ago, in graphene. In the past three years, we have achieved close to all that we proposed and more. *We have discovered nanotube-like ballistic transport in graphene nanoribbons * We demonstrated a novel form or transport in these ribbons, involving a single channel and we possibly may have discovered non-conventional, short-lived charge carriers (trions). * We demonstrated one-dimensional ferromagnetism with spintronics potential. * We have achieved the highest operational frequency in graphene transistors.
