Abstract

We present a detailed comparison of electron transport through triple electric-barrier structures and triple magnetic-barrier structures. Tunneling through triple electric-barrier structures is mainly determined by the momentum along the tunneling direction, while in triple magnetic-barrier structures transport strongly depends not only on structural parameters but also the transverse momentum. It is confirmed that both the transmission coefficient and the conductance are dramatically reduced with increasing height or width of the middle barrier in triple magnetic-barrier structures.
