In this paper, a simple method is proposed to get analytical solutions (or with the help of a few
numerical calculations) of the Dirac-Weyl equation for low energy electrons in graphene in the
presence of certain electric and magnetic fields. In order to decouple the Dirac-Weyl equation we have
assumed a displacement symmetry of the system along a direction and some conditions on the
magnetic and electric fields. The resulting equations have the natural form to apply the technique of
supersymmetric quantum mechanics. The example of an electric well with square profile is worked
out in detail to illustrate some of the most interesting features of this procedure.
