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…
Giant ratchet magneto-photocurrent in graphene lateral superlattices
S. Hubmann, V. V. Bel'kov, L. E. Golub +5
We report on the observation of the magnetic quantum ratchet effect in graphene with a lateral dual-grating top gate (DGG) superlattice. We show that the THz ratchet current exhibi…
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…
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…
Magnetotransport in heterostructures of transition metal dichalcogenides and graphene
Tobias Völkl, Tobias Rockinger, Martin Drienovsky +4
We use a van-der-Waals pickup technique to fabricate different heterostructures containing WSe(WS) and graphene. The heterostructures were structured by plasma etching, con…
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…
Towards superlattices: Lateral bipolar multibarriers in graphene
Martin Drienovsky, Franz-Xaver Schrettenbrunner, Andreas Sandner +5
We report on transport properties of monolayer graphene with a laterally modulated potential profile, employing striped top gate electrodes with spacings of 100 nm to 200 nm. Tunin…
