Rippled Graphene in an In-Plane Magnetic Field: Effects of a Random Vector Potential
arXiv:0910.4413 · doi:10.1103/PhysRevLett.105.146804
Abstract
We report measurements of the effects of a random vector potential generated by applying an in-plane magnetic field to a graphene flake. Magnetic flux through the ripples cause orbital effects: phase-coherent weak localization is suppressed, while quasi-random Lorentz forces lead to anisotropic magnetoresistance. Distinct signatures of these two effects enable an independent estimation of the ripple amplitude and correlation length.
Various changes; added appendix for Boltzmann calculation of anisotropic magnetoresistance
