Out-of-plane dielectric susceptibility of graphene in twistronic and Bernal bilayers
Sergey Slizovskiy, Aitor Garcia-Ruiz, Alexey I. Berdyugin +6
We describe how the out-of-plane dielectric polarizability of monolayer graphene influences the electrostatics of bilayer graphene -- both Bernal (BLG) and twisted (tBLG). We compa…
Control of electron-electron interaction in graphene by proximity screening
M. Kim, S. G. Xu, A. I. Berdyugin +14
Electron-electron interactions play a critical role in many condensed matter phenomena, and it is tempting to find a way to control them by changing the interactions' strength. One…
Minibands in twisted bilayer graphene probed by magnetic focusing
A. I. Berdyugin, B. Tsim, P. Kumaravadivel +9
Magnetic fields force ballistic electrons injected from a narrow contact to move along skipping orbits and form caustics. This leads to pronounced resistance peaks at nearby voltag…
Giant oscillations in a triangular network of one-dimensional states in marginally twisted graphene
S. G. Xu, A. I. Berdyugin, P. Kumaravadivel +12
The electronic properties of graphene superlattices have attracted intense interest that was further stimulated by the recent observation of novel many-body states at "magic" angle…
Micromagnetometry of two-dimensional ferromagnets
M. Kim, P. Kumaravadivel, J. Birkbeck +14
The study of atomically thin ferromagnetic crystals has led to the discovery of unusual magnetic behaviour and provided insight into the magnetic properties of bulk materials. Howe…
