We investigate low-temperature magneto-transport in recently developed, high-quality
multiterminal suspended bilayer graphene devices, enabling the independent measurement …

We analyze the phase diagram of the zeroth Landau level of bilayer graphene, taking into
account the realistic effects of screening of the Coulomb interaction and strong mixing …

This chapter introduces the problem of electron–electron interactions, briefly describes
several methods and their application to graphene quantum dots. The Hubbard model, the …

In ultra-clean two-dimensional electron systems (2DESs) subjected to a perpendicular
magnetic field (B), the transverse Hall conductance Gxy exhibits plateaus at fractions of e2/h …

Abstract Résumé: Nous étudions dans cette thèse plusieurs propriétés du gaz d'électrons
bidimensionnel (GE2D) dans le graphène et la bicouche de graphène (BG). Nous …

Graphene is a two-dimensional carbon material with a honeycomb lattice and Dirac-like low-
energy excitations. When Zeeman interaction is neglected its Landau levels are four-fold …

Two-dimensional electrons systems (2DES) exposed to strong magnetic fields at electron
den-sities above 10* 10 cm^{− 2}, such as those realized in AlGaAs/GaAs semiconductor …

The electronic properties of graphene are well described by a non-interacting Dirac
Hamiltonian with an internal symmetry associated with spin and valley, an additional degree …
