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…
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…
Flexuron, a self-trapped state of electron in crystalline membranes
M. I. Katsnelson
Self-trapping of an electron due to its interaction with bending fluctuations in a flexible crystalline membrane is considered. Due to the dependence of the electron energy on the…
Electronic Transport in Disordered Bilayer and Trilayer Graphene
Shengjun Yuan, Hans De Raedt, Mikhail I. Katsnelson
We present a detailed numerical study of the electronic transport properties of bilayer and trilayer graphene within a framework of single-electron tight-binding model. Various typ…
