Brown-Zak and Weiss oscillations in a gate-tunable graphene superlattice: A unified picture of miniband conductivity
Robin Huber, Max-Niklas Steffen, Martin Drienovsky +6
Electrons exposed to a two-dimensional (2D) periodic potential and a uniform, perpendicular magnetic field exhibit a fractal, self-similiar energy spectrum known as the Hofstadter…
Gate-tunable two-dimensional superlattices in graphene
Robin Huber, Ming-Hao Liu, Szu-Chao Chen +7
We report an efficient technique to induce gate-tunable two-dimensional superlattices in graphene by the combined action of a back gate and a few-layer graphene patterned bottom ga…
Edge currents driven by terahertz radiation in graphene in quantum Hall regime
H. Plank, M. V. Durnev, S. Candussio +9
We observe that the illumination of unbiased graphene in the quantum Hall regime with polarized terahertz laser radiation results in a direct edge current. This photocurrent is cau…
Commensurability Oscillations in One-Dimensional Graphene Superlattices
Martin Drienovsky, Jonas Joachimsmeyer, Andreas Sandner +6
We report the experimental observation of commensurability oscillations (COs) in 1D graphene superlattices. The widely tunable periodic potential modulation in hBN encapsulated gra…
Few-layer graphene patterned bottom gates for van der Waals heterostructures
Martin Drienovsky, Andreas Sandner, Christian Baumgartner +6
We introduce a method of local gating for van der Waals heterostructures, employing a few-layer graphene patterned bottom gate. Being a member of the 2D material family, few-layer…
Ballistic transport in graphene antidot lattices
Andreas Sandner, Tobias Preis, Christian Schell +5
Graphene samples can have a very high carrier mobility if influences from the substrate and the environment are minimized. Embedding a graphene sheet into a heterostructure with he…
