Influence of disordered edges on transport properties in graphene
D. Smirnov, G. Yu. Vasileva, J. C. Rode +4
The influence of plasma etched sample edges on electrical transport and doping is studied. Through electrical transport measurements the overall doping and mobility are analyzed fo…
Linear magnetoresistance in compensated graphene bilayer
G. Yu. Vasileva, D. Smirnov, Yu. L. Ivanov +8
We report a nonsaturating linear magnetoresistance in charge-compensated bilayer graphene in a temperature range from 1.5 to 150 K. The observed linear magnetoresistance disappears…
Magnetoresistance of monolayer graphene with short-range scattering
G. Yu. Vasileva, P. S. Alekseev, Yu. B. Vasilyev +4
We present magnetotransport measurements at classical magnetic fields for three graphene monolayers with various levels of disorder. A square root magnetoresistance (SRMR) behavior…
Superlattice structures in twisted bilayers of folded graphene
Hennrik Schmidt, Johannes C. Rode, Dmitri Smirnov +1
The electronic properties of bilayer graphene strongly depend on relative orientation of the two atomic lattices. Whereas Bernal-stacked graphene is most commonly studied, a rotati…
Suppression of decoherence in a graphene monolayer ring
Dmitri Smirnov, Johannes C. Rode, Rolf J. Haug
The influence of high magnetic fields on coherent transport is investigated. A monolayer graphene quantum ring is fabricated and the Aharonov-Bohm effect is observed. For increased…
Mixing of Edge States at a Bipolar Graphene Junction
H. Schmidt, J. C. Rode, C. Belke +2
An Atomic Force Microscope is used to locally manipulate a single layer graphene sheet. Transport measurements in this region as well as in the unmanipulated part reveal different…
Aharonov-Bohm effect in an electron-hole graphene ring system
D. Smirnov, H. Schmidt, R. J. Haug
Aharonov-Bohm oscillations are observed in a graphene quantum ring with a top gate covering one arm of the ring. As graphene is a gapless semiconductor this geometry allows to stud…
