Band gap and broken chirality in single-layer and bilayer graphene
Anastasia Varlet, Ming-Hao Liu, Dominik Bischoff +6
Chirality is one of the key features governing the electronic properties of single- and bilayer graphene: the basics of this concept and its consequences on transport are presented…
Tunable Fermi surface topology and Lifshitz transition in bilayer graphene
Anastasia Varlet, Marcin Mucha-Kruczyński, Dominik Bischoff +6
Bilayer graphene is a highly tunable material: not only can one tune the Fermi energy using standard gates, as in single-layer graphene, but the band structure can also be modified…
Measuring the local quantum capacitance of graphene using a strongly coupled graphene nanoribbon
D. Bischoff, M. Eich, A. Varlet +3
We present electrical transport measurements of a van-der-Waals heterostructure consisting of a graphene nanoribbon separated by a thin boron nitride layer from a micron-sized grap…
Capacitive coupling in hybrid Graphene-GaAs nanostructures
Pauline Simonet, Clemens Rössler, Tobias Krähenmann +5
Coupled hybrid nanostructures are demonstrated using the combination of lithographically patterned graphene on top of a two-dimensional electron gas (2DEG) buried in a GaAs/AlGaAs…
Graphene nanoribbons: relevance of etching process
Pauline Simonet, Dominik Bischoff, Annina Moser +2
Most graphene nanoribbons in the experimental literature are patterned using plasma etching. Various etching processes induce different types of defects and do not necessarily resu…
