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…
Magnetophonon spectroscopy of Dirac Fermion scattering by transverse and longitudinal acoustic phonons in graphene
M. T. Greenaway, R. Krishna Kumar, P. Kumaravadivel +2
Recently observed magnetophonon resonances in the magnetoresistance of graphene are investigated using the Kubo formalism. This analysis provides a quantitative fit to the experime…
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…
Strong magnetophonon oscillations in extra-large graphene
P. Kumaravadivel, M. T. Greenaway, D. Perello +8
Van der Waals materials and their heterostructures offer a versatile platform for studying a variety of quantum transport phenomena due to their unique crystalline properties and t…
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…
