Graphene Bilayer with a Twist: Electronic Structure [PDF]
Physical Review Letters, 2007 Electronic properties of bilayer and multilayer graphene have generally been interpreted in terms of AB or Bernal stacking. However, it is known that many types of stacking defects can occur in natural and synthetic graphite; rotation of the top layer is often seen in scanning tunneling microscopy (STM) studies of graphite.

Topologically Protected Zero Modes in Twisted Bilayer Graphene
, 2011 We show that the twisted graphene bilayer can reveal unusual topological properties at low energies, as a consequence of a Dirac-point splitting. These features rely on a symmetry analysis of the electron hopping between the two layers of graphene and we

Breakdown of the interlayer coherence in twisted bilayer graphene
, 2012 Coherent motion of the electrons in the Bloch states is one of the fundamental concepts of the charge conduction in solid state physics. In layered materials, however, such a condition often breaks down for the interlayer conduction, when the interlayer ...

Strain-induced Evolution of Electronic Band Structures in a Twisted Graphene Bilayer
, 2013 Here we study the evolution of local electronic properties of a twisted graphene bilayer induced by a strain and a high curvature. The strain and curvature strongly affect the local band structures of the twisted graphene bilayer; the energy difference ...

Quantum Hall Effect, Screening and Layer-Polarized Insulating States in Twisted Bilayer Graphene [PDF]
, 2011 We investigate electronic transport in dual-gated twisted bilayer graphene. Despite the sub-nanometer proximity between the layers, we identify independent contributions to the magnetoresistance from the graphene Landau level spectrum of each layer.
