Automated Machine Learning in Practice: State of the Art and Recent Results
Lukas Tuggener, Mohammadreza Amirian, Katharina Rombach +4
A main driver behind the digitization of industry and society is the belief that data-driven model building and decision making can contribute to higher degrees of automation and m…
Oscillating magnetoresistance in graphene p-n junctions at intermediate magnetic fields
Hiske Overweg, Hannah Eggimann, Ming-Hao Liu +10
We report on the observation of magnetoresistance oscillations in graphene p-n junctions. The oscillations have been observed for six samples, consisting of single-layer and bilaye…
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…
Electronic triple-dot transport through a bilayer graphene island with ultrasmall constrictions
Dominik Bischoff, Anastasia Varlet, Pauline Simonet +2
A quantum dot has been etched in bilayer graphene connected by two small constrictions to the leads. We show that this structure does not behave like a single quantum dot but consi…
Fabry-Pérot interference in gapped bilayer graphene with broken anti-Klein tunneling
Anastasia Varlet, Ming-Hao Liu, Viktor Krueckl +7
We report the experimental observation of Fabry-Pérot (FP) interference in the conductance of a gate-defined cavity in a dual-gated bilayer graphene (BLG) device. The high quality…
Anomalous sequence of quantum Hall liquids revealing tunable Lifshitz transition in bilayer graphene
Anastasia Varlet, Dominik Bischoff, Pauline Simonet +6
Fermi surface topology plays an important role in determining the electronic properties of metals. In bulk metals, the Fermi energy is not easily tunable at the energy scale needed…
