Uniform pseudomagnetic fields in graphene: corrections due to lattice deformations

Abstract

Very recently, the standard description of electrons in strained graphene has been completed by the explicit inclusion of the lattice deformation. Here, the effect of these lattice corrections is taken into account to find the mechanical deformations that generate a uniform pseudomagnetic field inside strained graphene. The main difference when compared with previous proposals in a rectangular geometry, is the need to stretch both zigzag and armchair edges.

arXiv commentThis paper has been withdrawn by the author since it's based on the equations of strained graphene using the Dirac approach. There is a debate going on concerning the use of these equations, so we prefer to wait until a consensus is reached. We will update this manuscript with some fixes to the strain equations as soon as possible
