Quantum Hall Effect and Quantum Point Contact in Bilayer-Patched Epitaxial Graphene
C. J. Chua, M. R. Connolly, A. Lartsev +10
We study an epitaxial graphene monolayer with bilayer inclusions via magnetotransport measurements and scanning gate microscopy at low temperatures. We find that bilayer inclusions…
Doping of epitaxial graphene on SiC intercalated with hydrogen and its magneto-oscillations
S. Kopylov, V. I. Fal'ko, Th. Seyller
We study the charge transfer between a quasi-free-standing monolayer graphene, produced by hydrogen intercalation, and surface acceptor states. We consider two models of acceptor d…
Transport anomaly at the ordering transition for adatoms on graphene
Sergey Kopylov, Vadim Cheianov, Boris L. Altshuler +1
We analyze a manifestation of the partial ordering transition of adatoms on graphene in resistivity measurements. We find that Kekule mosaic ordering of adatoms increases sheet res…
Anomalously strong pinning of the filling factor nu=2 in epitaxial graphene
T. J. B. M. Janssen, A. Tzalenchuk, R. Yakimova +4
We explore the robust quantization of the Hall resistance in epitaxial graphene grown on Si-terminated SiC. Uniquely to this system, the dominance of quantum over classical capacit…
Charge transfer between epitaxial graphene and silicon carbide
Sergey Kopylov, Alexander Tzalenchuk, Sergey Kubatkin +1
We analyse doping of graphene grown on SiC in two models which differ by the source of charge transfered to graphene, namely, from SiC surface and from bulk donors. For each of the…
