Moiré ordered current loops in the graphene twist bilayer
D. Weckbecker, M. Fleischmann, R. Gupta +6
While a typical material exhibits field induced currents only at the boundary, a uniform out-of-plane magnetic field applied to two mutually rotated layers of graphene is shown to…
Dislocation and node states in bilayer graphene systems
D. Weckbecker, R. Gupta, F. Rost +2
We investigate the electronic structure of realistic partial dislocation networks in bilayer graphene that feature annihilating, wandering, and intersecting partial lines. We find…
Moiré edge states in twisted graphene nanoribbons
M. Fleischmann, R. Gupta, D. Weckbecker +4
The edge physics of graphene based systems is well known to be highly sensitive to the atomic structure at the boundary, with localized zero mode edge states found only on the zigz…
Electron-phonon scattering and in-plane electric conductivity in twisted bilayer graphene
N. Ray, M. Fleischmann, D. Weckbecker +3
We have surveyed the in-plane transport properties of the graphene twist bilayer using (i) a low-energy effective Hamiltonian for the underlying electronic structure, (ii) an isotr…
Going beyond k.p theory: a general method for obtaining effective Hamiltonians in both high and low symmetry situations
N. Ray, F. Rost, D. Weckbecker +5
We provide a method for the generation of effective continuum Hamiltonians that goes beyond the well known k.p method in being equally effective in both high, and low (or no) symme…
