Exploiting Aharonov-Bohm oscillations to probe Klein tunneling in tunable pn-junctions in graphene
Jan Dauber, Koen J. A. Reijnders, Luca Banszerus +6
One of the unique features of graphene is that the Fermi wavelength of its charge carriers can be tuned electrostatically over a wide range. This allows in principle to tune the tr…
Aharonov-Bohm oscillations and magnetic focusing in ballistic graphene rings
Jan Dauber, Martin Oellers, Florian Venn +5
We present low-temperature magnetotransport measurements on graphene rings encapsulated in hexagonal boron nitride. We investigate phase-coherent transport and show Aharonov-Bohm (…
Ultra-sensitive Hall sensors based on graphene encapsulated in hexagonal boron nitride
Jan Dauber, Abhay A. Sagade, Martin Oellers +4
The encapsulation of graphene in hexagonal boron nitride provides graphene on substrate with excellent material quality. Here, we present the fabrication and characterization of Ha…
Reducing disorder in graphene nanoribbons by chemical edge modification
Jan Dauber, Bernat Terrés, Christian Volk +2
We present electronic transport measurements on etched graphene nanoribbons on silicon dioxide before and after a short hydrouoric acid (HF) treatment. We report on changes in the…
Transport in coupled graphene-nanotube quantum devices
S. Engels, P. Weber, B. Terrés +6
We report on the fabrication and characterization of all-carbon hybrid quantum devices based on graphene and single-walled carbon nanotubes. We discuss both, carbon nanotube quantu…
Charge detection in a bilayer graphene quantum dot
Stefan Fringes, Christian Volk, Caroline Norda +5
We show measurements on a bilayer graphene quantum dot with an integrated charge detector. The focus lies on enabling charge detection with a 30 nm wide bilayer graphene nanoribbon…
