Abstract. The aim of this work is a theoretical study of the conductivity of a two-dimensional graphene-based superlattice taking into account the ionization of impurity centers within the framework of the semiclassical approach. A difference between the direction of the current density vector and the vector of the constant electric field strength in strong electric fields (the Sasaki-Shibuya effect) is discovered. The dependence of the angle j between these vectors on the angle of rotation of the constant electric field strength vector is studied. It is considered how the j changes if an alternating electric field additionally acts on the structure.

Key words: two-dimensional graphene superlattice, current density, Sasaki-Shibuya effect, impurity ionization.
