Abstract

We research the transport properties on a three-region structure of the bulk Weyl semimetals. We show the change of electron scattering with field b₀ in center transport region when electrons pass through the center transport region. A valley is filtered when b₀ is near Fermi energy E_F by calculating valley-resolved transmission probability and valley-resolved reflection probability of Weyl electrons. We also research the influence of short-range disorders on valley transport property. These results can not only contribute to the comprehending of Weyl semimetals and valleytronics, but also provide a feasible method to design valley filter in view of the Weyl semimetals.
