Abstract
To understand the influence of different mean free paths between adjacent materials on diffusive scatterings of a transport electron, we study an A-B bilayer with two infinite planes by use of the linear response Boltzmann transport equation in the relaxation time approximation with given boundary conditions. Our theoretical results show that the asymmetry in the mean free path induces a directional interfacial diffusive scattering when the electrons transport across the A-B interface.
