Friedel Oscillation-Induced Energy Gap Manifested as Transport Asymmetry at Monolayer-Bilayer Graphene Boundaries
Kendal W. Clark, X. -G. Zhang, Gong Gu +4
We show that Friedel charge oscillation near an interface opens a gap at the Fermi energy for electrons with wave vectors perpendicular to the interface. If the Friedel gaps on two…
SymFET: A Proposed Symmetric Graphene Tunneling Field Effect Transistor
Pei Zhao, Randall M. Feenstra, Gong Gu +1
In this work, an analytical model to calculate the channel potential and current-voltage characteristics in a Symmetric tunneling Field-Effect-Transistor (SymFET) is presented. The…
Single-Particle Tunneling in Doped Graphene-Insulator-Graphene Junctions
R. M. Feenstra, Debdeep Jena, Gong Gu
The characteristics of tunnel junctions formed between n- and p-doped graphene are investigated theoretically. The single-particle tunnel current that flows between the two-dimensi…
Morphology of Graphene on SiC(000-1) Surfaces
Luxmi, P. J. Fisher, N. Srivastava +5
Graphene is formed on SiC(000-1) surfaces (the so-called C-face of the crystal) by annealing in vacuum, with the resulting films characterized by atomic force microscopy, Auger ele…
