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…
Observation of the spin-orbit gap in bilayer graphene by one-dimensional ballistic transport
L. Banszerus, B. Frohn, T. Fabian +10
We report on measurements of quantized conductance in gate-defined quantum point contacts in bilayer graphene that allow the observation of subband splittings due to spin-orbit cou…
Extraordinary high room-temperature carrier mobility in graphene-WSe heterostructures
L. Banszerus, T. Ouaj, T. Sohier +16
High charge carrier mobilities play a fundamental role for high-frequency electronics, integrated optoelectronics as well as for sensor and spintronic applications, where device pe…
Insulating state in low-disorder graphene nanoribbons
A. Epping, C. Volk, F. Buckstegge +3
We report on quantum transport measurements on etched graphene nanoribbons encapsulated in hexagonal boron nitride (hBN). At zero magnetic field our devices behave qualitatively ve…
Gate-defined electron-hole double dots in bilayer graphene
Luca Banszerus, Benedikt Frohn, Alexander Epping +4
We present gate-controlled single, double, and triple dot operation in electrostatically gapped bilayer graphene. Thanks to the recent advancements in sample fabrication, which inc…
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 (…
