Graphene Dirac fermions in symmetric electric and magnetic fields: the case of an electric square well

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