Giant ultra-broadband photoconductivity in twisted graphene heterostructures
Hitesh Agarwal, Krystian Nowakowski, Andres Forrer +12
The requirements for broadband photodetection are becoming exceedingly demanding in hyperspectral imaging. Whilst intrinsic photoconductor arrays based on mercury cadmium telluride…
Graphene's non-equilibrium fermions reveal Doppler-shifted magnetophonon resonances accompanied by Mach supersonic and Landau velocity effects
M. T. Greenaway, P. Kumaravadivel, J. Wengraf +6
Oscillatory magnetoresistance measurements on graphene have revealed a wealth of novel physics. These phenomena are typically studied at low currents. At high currents, electrons a…
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…
Superballistic flow of viscous electron fluid through graphene constrictions
R. Krishna Kumar, D. A. Bandurin, F. M. D. Pellegrino +13
Electron-electron (e-e) collisions can impact transport in a variety of surprising and sometimes counterintuitive ways. Despite strong interest, experiments on the subject proved c…
