Two-dimensional Mott-Hubbard electrons in an artificial honeycomb lattice
A. Singha, M. Gibertini, B. Karmakar +8
Electrons in artificial lattices enable explorations of the impact of repulsive Coulomb interactions in a tunable system. We have trapped two-dimensional electrons belonging to a g…
Coulomb drag in graphene single layers separated by a thin spacer
M. I. Katsnelson
Motivated by very recent studies of Coulomb drag in grahene-BN-graphene system we develop a theory of Coulomb drag for the Fermi liquid regime, for the case when the ratio of space…
Giant Nonlocality near the Dirac Point in Graphene
D. A. Abanin, S. V. Morozov, L. A. Ponomarenko +8
Transport measurements have been a powerful tool for uncovering new electronic phenomena in graphene. We report nonlocal measurements performed in the Hall bar geometry with voltag…
Excitation spectrum and high energy plasmons in single- and multi-layer graphene
Shengjun Yuan, Rafael Roldán, Mikhail I. Katsnelson
In this paper we study the excitation spectrum of single- and multi-layer graphene beyond the Dirac cone approximation. The dynamical polarizability of graphene is computed using a…
Temperature dependent resistivity in bilayer graphene due to flexural phonons
H. Ochoa, Eduardo V. Castro, M. I. Katsnelson +1
We have studied electron scattering by out-of-plane (flexural) phonons in doped suspended bilayer graphene. We have found the bilayer membrane to follow the qualitative behavior of…
Quantum transport via evanescent waves in undoped graphene
M. I. Katsnelson
Charge carriers in graphene are chiral quasiparticles ("massless Dirac fermions"). Graphene provides therefore an amazing opportunity to study subtle quantum relativistic effects i…
