Imaging Hydrodynamic Electrons Flowing Without Landauer-Sharvin Resistance
Chandan Kumar, John Birkbeck, Joseph A. Sulpizio +8
Electrical resistance usually originates from lattice imperfections. However, even a perfect lattice has a fundamental resistance limit, given by the Landauer conductance caused by…
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…
Out-of-equilibrium criticalities in graphene superlattices
Alexey I. Berdyugin, Na Xin, Haoyang Gao +19
In thermodynamic equilibrium, current in metallic systems is carried by electronic states near the Fermi energy whereas the filled bands underneath contribute little to conduction.…
Exponentially selective molecular sieving through angstrom pores
P. Z. Sun, M. Yagmurcukardes, R. Zhang +8
Two-dimensional crystals with angstrom-scale pores are widely considered as candidates for a next generation of molecular separation technologies aiming to provide extreme, exponen…
