High-Performance Top-Gated Graphene-Nanoribbon Transistors Using Zirconium Oxide Nanowires as High-Dielectric-Constant Gate Dielectrics

A new strategy for integrating high-dielectric-constant (high-k) dielectrics with graphene nanoribbon (GNR) is presented. Freestanding zirconium oxide nanowires are synthesized and subsequently assembled on top of GNRs as high-k gate dielectrics for top-gated GNR transistors with unprecedented performance. [GRAPHICS] .
