| In this paper we consider the influence of "mass barrier" and elastic scattering processes on the shape of j(V) and j(B) characteristics. Two scattering mechanisms, i.e. Coulombic on ionized impurities and on potential fluctuations in double-barrier structures are considered. The "mass barrier" shifts the whole j(V) characteristic slightly towards lower voltage and makes the resonant energy ER dependent on magnetic field. On the other hand, both considered scattering mechanisms change the shape of j(V) and j(B) characteristics by shifting the oscillation maxima towards lower applied voltage. |
