Annotation A two-dimensional square superlattice is considered, which electron spectrum is described in the tight-binding approximation. The conditions of the semiclassical situation and the applicability of the Boltzmann equation are assumed to be satisfied. The sample in the form of a rectangle is cut out so that its sides form an angle  with the main axes of the superlattice. A constant (pulling) electric field is applied along the direction of one of the sides of the sample. It is shown that in certain situations the appearence of a transverse electric field with respect to the pulling field is possible. The dependence of the value of the transverse field on the angle of rotation  was studied for several specified values of the pulling field.
